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.
