Evolution of the obliquity of an exoplanet: A non-resonant case
Icarus, 2020We investigate analytically and numerically the variation of the obliquity (the axial tilt) of a hypothetical exo-Earth. A large number of exoplanets was discovered recently; since not much information is available about the masses and orbits of the ...

Haze evolution in temperate exoplanet atmospheres through surface energy measurements [PDF]
Nature Astronomy, 2021 Photochemical hazes are important opacity sources in temperate exoplanet atmospheres, hindering current observations from characterizing exoplanet atmospheric compositions.

Exoplanet Statistics and Theoretical Implications [PDF]
Annual Review of Astronomy and Astrophysics, 2021 In the past few years, significant advances have been made in understanding the distributions of exoplanet populations and the architecture of planetary systems.

The Possible Evolution of an Exoplanet’s Atmosphere
Eos, 2021 Scientific sleuths explore data gathered trillions of kilometers away and put forth different, and often conflicting, ideas to reconstruct the gaseous envelope on a distant rocky exoplanet, GJ 1132 b.

The effect of galactic chemical evolution on terrestrial exoplanet composition and tectonics
Icarus, 2020The increasing exoplanet catalogue of terrestrial to super-Earth sized rocky planets has necessitated approaches to address their surface conditions, degassing, tectonics, and habitability.

Atmospheric Escape and the Evolution of Close-In Exoplanets [PDF]
Annual Review of Earth and Planetary Sciences, 2019 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.

Spin-Orbital Evolution of Exoplanets
EAS Publications Series, 2003We investigated the equation describing the evolution of the kinetic momentum vector of planets by the action of gravitational and magnetic interaction. The obtained gallery of portraits of the kinetic momentum evolution illustrates the various regimes of planetary system evolution.

Silicate clouds and a circumplanetary disk in the YSES-1 exoplanet system
NatureYoung exoplanets provide an important link between understanding planet formation and atmospheric evolution1. Direct imaging spectroscopy allows us to infer the properties of young, wide-orbit, giant planets with high signal-to-noise ratio.

Effect of Galactic Chemical Evolution on Exoplanet Properties
Astrophysical Journal LettersAbstract We couple a simplified model for galactic chemical evolution with software that models the condensation of dust in protoplanetary disks and software that models the interior structure of planets, in order to estimate the effects that galactic chemical evolution has on the properties of planets as they form over time.
