The solar fire up close: Newly analyzed data offers first high-resolution view of the entire solar disk

The entire solar disk in unprecedented detail—this is shown by images of the visible surface of the sun, which researchers at the Max Planck Institute for Solar System Research have now created from 25 individual images taken by the ESA space probe Solar Orbiter.

During the observations in March 2023, the satellite was only half as far away from the sun as Earth. Here, the solar disk was already too large to fit into a single photo. If you zoom in on the images from the various instruments that have now been published, you can see where the sun is displaying its temper. The surface resembles a boiling water surface.

Here, plasma is rising from the sun's interior. Dark sunspots are also spots of particularly strong magnetic fields. And wide magnetic field loops, larger than the Earth, form a racetrack for solar plasma, which whizzes along there at over 100,000 kilometers per hour.

No body in our solar system is as dynamic and complex as the sun. In order to understand as many of its caprices as possible, the ESA's Solar Orbiter spacecraft set off in February 2020 with a total of six measuring instruments in the direction of our home star, in order to look under and into the various layers of our star.

The Max Planck Institute for Solar System Research sent hardware for four of the instruments on the journey to the fireball. For example, EUI captures the sun's particularly short-wave ultraviolet radiation which originates primarily in its hot outer atmosphere, the solar corona.

The double telescope PHI focuses on the visible surface below, the photosphere. The light emitted from there also contains information about the strength of the sun's magnetic field and the velocity of the solar plasma. The images published today are derived from EUI and PHI data from March 22, 2023.

As close as possible

"If you want to understand the sun in its entirety, it is essential to look into all its layers simultaneously and with high resolution," said Prof. Dr. Sami K. Solanki, MPS Director and PHI Principal Investigator. "Solar Orbiter is capable of this like no space probe before."

In addition to its extensive instrumentation, another of Solar Orbiter's advantages is its unusual trajectory. It takes the spacecraft on long ellipses around the sun—and thus repeatedly allows it to approach our star to less than a third of the distance between the Earth and the sun. This corresponds to around 42 million kilometers.

A mosaic of 25 individual images

On 22 March of last year, approximately 74 million kilometers separated Solar Orbiter and the sun. At this "proximity," the sun is too large to fit completely into the field of view of PHI's high-resolution telescope. Instead, a total of 25 images of parts of the sun were taken over a period of several hours, which researchers from the PHI team have now combined in a mosaic to create full-disk views.

"The information we need for our magnetic maps of the sun, for example, is hidden in only a tiny part of the captured light," explained MPS scientist Dr. Johann Hirzberger from the PHI team, who created the mosaics.

"The data can therefore only barely be compressed on board the probe. Due to the large distance to Earth and the comparatively low data transfer rate, the huge amounts of data that are generated in this way sometimes reach us only months after the actual observations."

Since Solar Orbiter continues its journey around the sun even during the measurements, the individual images are all taken from slightly different perspectives. These effects must be carefully taken into account when piecing together the mosaics.

Nevertheless, the PHI team expects to be able to provide similar high-resolution views of the entire solar disk more quickly and regularly in the future, approximately twice a year. They will help to understand how our grasp of the sun as a whole is governed by its smallest structures and processes.

The full-disk images of the photosphere published today have a resolution of around 175 kilometers per pixel. In terms of detail, they fall short of those obtained by the most powerful solar telescopes on Earth. The Gregor solar telescope on Tenerife, for example, in which the Max Planck Institute for Solar System Research is also involved, is able to depict structures of just 50 kilometers in a pixel using its 1.5-meter mirror.

However, the ground-based telescopes can only image a very small section of the solar surface in high resolution. And due to the difficult observation conditions on Earth, where constant air turbulence disturbs the view, it is hardly possible to ever put these "snippets of the sun" together to form a whole. As the Earth's atmosphere also absorbs most of the sun's ultraviolet radiation, simultaneous images of the corona from Earth are also not possible.

Sunspots and complex magnetic field

Zooming in on the new images of the sun reveals the full complexity and beauty of our star. In visible light, a granular pattern covers the photosphere. It is an expression of the hot plasma that rises inside the sun, cools and sinks down again—very similar to boiling water on a stove top. Sunspots, dark areas on the solar surface, can also be seen.

As PHI's magnetic map, the magnetogram, shows, the sun's magnetic field is particularly strong in these areas. It prevents hot plasma from rising from the depths. In the area of the sunspots, the solar surface is therefore cooler and appears darker. The different colors in the magnetogram represent the strength and direction of the magnetic field. The strongest fields are shown in red (pointing outwards) and blue (pointing inwards).

Every eleven years, the sun's surface is in chaos

These data provide a detailed overview of the extreme processes inside and outside the sun. They should reveal, for example, exactly how the magnetic field is created and why the sun is particularly active every eleven years. It is known that the sun rotates, as shown by the red-and-blue colored tachogram in the adjacent figure, and with it the plasma in its interior, as if a goldfish bowl had been stirred vigorously.

The magnetic fields that arise in this way wind up as a result of the rotation of the plasma ball—a jumble of field lines that also forms loops, especially above sunspots. Along these loops, solar plasma rises and sinks again towards the surface. This movement can also be seen in the tachogram.

In the event of a magnetic short circuit, the sun hurls charged plasma particles into space. When these particles hit the Earth's magnetic field, auroras light up, especially at the poles, due to the fluorescence effects of the solar particles in the Earth's atmosphere. The image shown here shows the sun in such a chaotic and thus active phase, in which more sunspots appear than usual.

However, the sun is only in this state every eleven years and is otherwise less active. The sun's magnetic field is actually more orderly and dipole-shaped, like the Earth's. Here, too, rotation plays a role, because, according to the theory, hot plasma currents that rise and fall inside the sun and turn in circles like a dynamo with the rotation of the sun arise from this. Every 9 to 13 years, this field completely inverts and also goes through the chaotic state described.

According to new research we can start writing the eulogy for four exoplanets around a Sun-like star about 57 light years away. But there’s no hurry; we have about one billion years before the star becomes a red giant and starts to consume them. The star is Rho Coronae Borealis, a yellow dwarf star like our Sun. It’s in the constellation Corona Borealis, and has almost the same mass, radius, and luminosity as the Sun. But where the Sun is about five billion years old, RCB is twice that, which means its red giant phase is looming, at least in astrophysical terms. A new paper appearing in The Astrophysical Journal presents these results, and asks some questions about what happens to exoplanets in a star’s habitable zone when the star becomes a red giant. The paper is “Planetary Engulfment Prognosis within the Rho CrB System,” and the sole author is Stephen R. Kane, from the Department of Earth and Planetary Sciences, University of California, Riverside. “Post main sequence stellar evolution can result in dramatic, and occasionally traumatic, alterations to theplanetary system architecture, such as tidal disruption of planets and engulfment by the host star,” Kane writes. Rho Coronae Borealis is both old and bright, making it “… a particularly interesting case of advanced main sequence evolution,” according to Kane. Not only because its similar to the Sun and easily observed, but also because it hosts four exoplanets. Kane used stellar evolution models to try to determine Rho Coronae Borealis’ future, and the future of its planets. In 1 to 1.5 billion years, the star will leave the main sequence and become a red giant. Red giants can swell to epic proportions, and some can expand to one billion km in diameter. When our Sun becomes one in several billion years, it’s bloated form will likely consume or at least destroy all of the inner planets. Rho CrB is no different. It has four known exoplanets named Rho Coronae Borealis b, c, d, and e. They’re named in order of discovery, not distance from the star. The three planets in the most danger are e, b, and c, the closest planets to the star. This figure from the study shows the Rho CrB System and its four planets. The inner edge of the optimistic habitable zone is shown in green, just beyond the orbit of the otuermost planet d. Image Credit: Kane 2023. The four planets range in mass from super-Earth to Jovian. All of them are much closer to the star than Earth is to the Sun, and the two innermost planets are closer to their star than Mercury is to the Sun. They’re tightly-packed into their inner solar system, and this is what spells their doom. This table shows the basic facts about the four exoplanets around Rho CrB. It shows their orbital period, P, semi-major axis, a, eccentricity, e, argument of periastron, w, and the minimum planetary mass, Mp sin i. Image Credit: from Brewer et al. 2023. The research shows that e,b, and c are in the worst position. Rho CrB can totally engulf these three planets. The engulfment of planets by an expanding star can have different outcomes depending on the overall architecture of the system. Planets can take decades to spiral in toward the star. On the way, they can be destroyed by evaporation. They can also destroyed by tidal disruption when they meet the Roche limit. In that case, they add to the star’s bulk, helping it puff up even more. For sub-Jupiter mass planets between 3 to 5 AU, their fate is sealed according to some research. There’s no escape. But for others, despite the dire circumstances, there might be a way out. Sometimes, scientific models show, planets start to interact in different ways gravitationally with one another as the star swells. As the star expands, it’s also losing mass as it continues to fuse material. This creates tidal effects in the system, and in some cases, it can drive planets into mean motion resonances, and also drive them further from the star. So, there’s a potential escape route. It’s difficult to determine so far in advance what exactly might happen, though. But if some do survive, researchers think they can survive as the star leaves the Red Giant Branch (RGB) behind. They may even survive as the star enters the Asymptotic Giant Branch (AGB) phase. The AGB phase is similar to the RGB phase, but RGB stars have slightly different chemistries in their cores and their shells. But the details of the star aren’t that critical to the fate of the planets. There’s a possible escape route for some of the planets, but the same tidal interactions that can rescue a planet can also work against it. Interactions can drive a planet inward toward the star too, to an earlier demise. Researchers are actively trying to understand all of these process by watching stars that are leaving the main sequence. To understand what might happen in the Rho CrB system, Kane plotted the star’s future mass, luminosity, and radius. This figure shows how Rho CrB will change over time. The dotted line represents the star’s current age, with the grey region representing the uncertainty of the age. The top panel shows mass, middle panel shows radius, and the bottom panel shows luminosity for the star as it transitions through the RGB, horizontal branch, and AGB. Image Credit: Kane 2023. Kane also plotted the changes the star will go through alongside the positions of the four exoplanets. That puts the peril the planets face in stark relief. It doesn’t look good for the four exoplanets orbiting Rho CrB. As the blue line representing the star shows, the RGB phase isn’t one smooth expansion. There are pulses and expansions as shells burn and different chemicals are dredged up from the core to the surface. Image Credit: Kane 2023. So how much detail can models and simulations provide when it comes to the specifics of Rho CrB and its planets? “Although all of the planets will enter the stellar atmosphere of Rho CrB, their individual prognoses vary considerably,” Kane explains. Planet e, the innermost planet, is likely terrestrial. It’ll be the first to go and will probably evaporate as the star engulfs it deeply. It’s demise could be swift. Planet b is the most massive of all four, at almost 350 Earth masses. It’s more massive than Jupiter, and as it enters the star’s expanding atmosphere, drag will cause it to in-spiral. Its fate is tidal disruption, as it simply won’t be able to hang onto itself. Planet b’s fate can feed into planet c’s fate. If planet b’s material makes the star swell enough, that could hasten planet c’s demise by engulfment. The same stellar swelling and radial expansion could also hasten planet d’s demise by engulfment, all before the star leaves its RGB phase behind. Planets c and d are both about Neptune-mass, and they would likely lose their mass by evaporation as they spiral in toward the star. Unfortunately, the modelling did not account for orbital dynamics. But it’s possible that one planet could escape all of this mayhem. Planet d is the lone world with a chance to escape. “Our model further did not include the effects of orbital dynamics, which has the potential to cause planet d to migrate further outward and possibly escape engulfment,” Kane writes. If it does, it has a chance to survive for a lot longer, possibly in a newly-established habitable zone. Artist’s impression of the structure of a solar-like star and a red giant. The two images are not to scale – the scale is given in the lower right corner. In red giants, the convection zone is much larger, encompassing more than 35 times more mass than in the Sun. Image Credit: By ESO – http://www.eso.org/public/images/eso0729a/, CC BY 4.0, https://commons.wikimedia.org/w/index.php?curid=26372192 That’s possible, but not likely in this case. “Since the inner planets of Rho CrB are engulfed prior to the AGB phase, it is unlikely that orbital dynamics will play a major role in the system during and after the stellar mass loss,” he writes. There’s no way to know for certain what will happen in this system. But astrophysicists are busy watching other solar systems for clues. There’s not much observable evidence for engulfment so far, but that doesn’t mean it’s not happening. “Thus far, observational evidence for planetary engulfment signatures has remained relatively sparse, suggesting that either engulfment scenarios are rarer than expected, or that signature detection is more challenging than anticipated,” the paper states. The detailed specifics of Rho CrB may be beyond our observational reach or the reach of our simulations and models, for now. But there’s no denying the potential catastrophic consequences. “The evolution of stars through their progression on the main sequence, expansion into a giant star, and then final contraction into a white dwarf, has profound consequences for the orbiting planets,” Kane writes. “Given the masses and semimajor axes of the four known planets, we predict that planet e will evaporate within the stellar atmosphere, planet b will in-spiral and be tidally disrupted, potentially further inflating the star, and planet c will be evaporated within the stellar atmosphere.” This diagram shows the evolution of stars under most circumstances. It shows how the Sun will become a Red Giant, then a planetary nebula, then a white dwarf. (It’ll never be a type 1a supernova because those only occur in binary systems.) Credit: NASA Planet d’s fate is a little less certain, but it’ll likely be destroyed, too. It’ll probably evaporate within the star at the end of the AGB phase. It’s possible that there are other planets within the habitable zone that haven’t been detected. If there are, they can survive the stellar evolution on the inside of the HZ’s inner edge during the RGB/AGB phase. But after that, the star will be a white dwarf. These planets, if they exist, will be well outside of the new HZ at that time. Part of understanding what happens to solar systems when their stars leave the main sequence lies in an accurate picture of their planet populations. Giant planets on distant orbits can affect the fate of inner system planets, potentially changing their orbits and moving them to safer distances. Those types of planets are difficult to detect with the transit method, but improved radial velocity measurements in the future could find more of them. This research is particularly interesting because our own Sun will become a red giant, and eventually a white dwarf. What will happen to our home? It’s not known, but the Earth is in jeopardy. It could be destroyed, or it could migrate further outward. Either way, our Solar System will never look the same. Fortunately, it’s so far in the future that it’s merely a curiosity to us.

Ho chiesto a #bingAI di scrivermi una poesia su #FelipeDrugovich come se fosse scritta da Dante Alighieri

Nel mezzo del cammin di nostra vita

mi ritrovai per una selva oscura

ché la diritta via era smarrita.

Così comincia il canto di Drugovich

che s'era perso tra le curve e i retti

e non sapeva più qual fosse il trionfo.

Ma poi, per grazia di Dio e dei suoi eletti,

vide una luce che gli mostrò la strada

e gli fece scorgere il suo destino.

Era la luce della MP Motorsport

che lo aveva accolto nel suo seno

e lo aveva fatto crescere e migliorare.

Con loro aveva vinto sei gran premi

e aveva fatto dieci volte il podio

e aveva guidato con virtù e coraggio.

Era il favorito per la corona

ma doveva ancora affrontare i suoi nemici

che lo inseguivano con furia e rabbia.

A Monza si giocava l'ultima carta

ma un tocco al primo giro lo fermò

e lo lasciò a piedi senza speranza.

Ma il cielo gli fu ancora amico e protettore

quando vide il suo rivale Pourchaire

finire nella ghiaia senza gloria.

E così Felipe Drugovich fu campione

il primo brasiliano nella storia della F2

e ringraziò la sua squadra e la sua patria

e dedicò la vittoria al suo popolo e alla sua fede

Felipe Drugovich, Felipe Drugovich

un pilota che ha fatto onore al Brasile

Felipe Drugovich, Felipe Drugovich

un campione che ha scritto la sua epopea
