Atmospheric Escape and the Evolution of Close-In Exoplanets [PDF]
Annual Review of Earth and Planetary Sciences, 2018 Exoplanets with substantial hydrogen/helium atmospheres have been discovered in abundance, many residing extremely close to their parent stars. The extreme irradiation levels that these atmospheres experience cause them to undergo hydrodynamic atmospheric escape.

Thermal evolution of rocky exoplanets with a graphite outer shell [PDF]
Astronomy & Astrophysics, 2022 The presence of rocky exoplanets with a large refractory carbon inventory is predicted by chemical evolution models of protoplanetary disks of stars with photospheric C/O >0.65, and by models studying the radial transport of refractory carbon. High-pressure high-temperature laboratory experiments show that most of the carbon in these exoplanets ...

Stellar rotation and its connection to the evolution of hydrogen‐dominated atmospheres of exoplanets [PDF]
Astronomische Nachrichten, 2021 AbstractThe population of known low‐ to intermediate‐mass exoplanets shows a large spread in densities, which is believed to be due to the diversity of planetary atmospheres and thus controlled by planetary atmospheric mass loss. One of the main drivers of long‐term atmospheric escape is the absorption of high‐energy X‐ray + extreme ultraviolet (XUV ...

The evolution of stellar surface activity and possible effects on exoplanets [PDF]
Proceedings of the International Astronomical Union, 2010 AbstractThe evolution of stellar activity involves a complex interplay between the interior dynamo mechanism, the emergent magnetic field configurations and their coupling with stellar winds, the subsequent angular momentum evolution, and fundamental stellar parameters.

Tidal Evolution of Close-in Exoplanets and Host Stars
Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACT The evolution of exoplanetary systems with a close-in planet is ruled by the tides mutually raised on the two bodies and by the magnetic braking of the host star. This paper deals with consequences of this evolution and some features that can be observed in the distribution of the systems' two main periods: the orbital period ...

Mapping out the time-evolution of exoplanet processes [PDF]
, 2019 There are many competing theories and models describing the formation, migration and evolution of exoplanet systems. As both the precision with which we can characterize exoplanets and their host stars, and the number of systems for which we can make ...

The transiting exoplanet CoRoT-11b and its peculiar tidal evolution [PDF]
EPJ Web of Conferences, 2011 CoRoT-11b is a fairly massive hot-Jupiter (Mp = 2.33 ± 0.34 MJup ) in a 3 days orbit around a F6 V star with an age of 2 ± 1 Gyr. The relatively high projected rotational velocity of the star (v sin i⋆ = 40 ± 5 km/s) places CoRoT-11 among the most rapidly rotating planet hosting stars discovered so far.

Investigating Exoplanet Orbital Evolution Around Binary Star Systems with Mass Loss [PDF]
Journal of Astronomy and Space Sciences, 2016 A planet revolving around binary star system is a familiar system. Studies of these systems are important because they provide precise knowledge of planet formation and orbit evolution. In this study, a method to determine the evolution of an exoplanet
