Evolution of exoplanets and their parent stars [PDF]

open access: yesEAS Publications Series, 2014
Studying exoplanets with their parent stars is crucial to understand their population, formation and history. We review some of the key questions regarding their evolution with particular emphasis on giant gaseous exoplanets orbiting close to solar-type stars.

The transiting exoplanet CoRoT-11b and its peculiar tidal evolution [PDF]

open access: diamondEPJ 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.

Analysis of the orbital evolution of exoplanets [PDF]

open access: yesComputational and Applied Mathematics, 2015
An exoplanet, or extrasolar planet, is a planet that does not orbit the Sun, but is around a different star, stellar remnant, or brown dwarf. Up to now, about 1900 exoplanets were discovered. To better understand the dynamics of these exoplanets, a study with respect to possible collisions of the planet with the central star is shown here.

Thermal and Orbital Evolution of Low-mass Exoplanets [PDF]

open access: yesThe Astrophysical Journal, 2020
Abstract The thermal, orbital, and rotational dynamics of tidally loaded exoplanets are interconnected by intricate feedback. The rheological structure of the planet determines its susceptibility to tidal deformation and, as a consequence, participates in shaping its orbit.

Exoplanet atmosphere evolution: emulation with neural networks

open access: yesMonthly Notices of the Royal Astronomical Society, 2023
ABSTRACT Atmospheric mass-loss is known to play a leading role in sculpting the demographics of small, close-in exoplanets. Knowledge of how such planets evolve allows one to ‘rewind the clock’ to infer the conditions in which they formed.

Colloquium: Physical constraints for the evolution of life on exoplanets [PDF]

open access: greenReviews of Modern Physics, 2019
Since the 1990s over 4000 exoplanets have been discovered: which of them could also develop and harbor life? It is posited that the planet must have liquid water, a surrounding atmosphere, and must be both biocompatible and possess the bioessential elements to be habitable.

EUV influences on exoplanet atmospheric stability and evolution

open access: green, 2019
The planetary effective surface temperature alone is insufficient to characterize exoplanet atmospheres and their stability or evolution. Considering the star-planet system as a whole is necessary, and a critical component of the system is the photoionizing stellar extreme ultraviolet emission (EUV; 100-912 ).

Understanding exoplanet formation, structure and evolution in 2010 [PDF]

open access: yesProceedings of the International Astronomical Union, 2010
AbstractIn this short review, we summarize our present understanding (and non-understanding) of exoplanet formation, structure and evolution, in the light of the most recent discoveries. Recent observations of transiting massive brown dwarfs seem to remarkably confirm the predicted theoretical mass-radius relationship in this domain.
