Cloud formation in exoplanet atmospheres : nucleation of small molecular clusters [PDF]
, 2023 It has been inferred that many exoplanets host clouds in their atmospheres. Understanding the processes through which these clouds form, and being able to model them is essential for our understanding of their climate and to explain our observations.

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

Evidence for Low-level Dynamical Excitation in Near-resonant Exoplanet Systems [PDF]
The Astronomical Journal, 2023 The geometries of near-resonant planetary systems offer a relatively pristine window into the initial conditions of exoplanet systems. Given that near-resonant systems have likely experienced minimal dynamical disruptions, the spin–orbit orientations of ...

Aerosols in Exoplanet Atmospheres [PDF]
, 2021 Observations of exoplanet atmospheres have shown that aerosols, like in the Solar System, are common across a variety of temperatures and planet types. The formation and distribution of these aerosols are inextricably intertwined with the composition and

Dynamical Evolution of Closely Packed Multiple Planetary Systems Subject to Atmospheric Mass Loss
The Astronomical Journal, 2023 A gap in exoplanets’ radius distribution has been widely attributed to the photoevaporation threshold of their progenitors’ gaseous envelope. Giant impacts can also lead to substantial mass loss.

Exoplanet Volatile Carbon Content as a Natural Pathway for Haze Formation
The Astrophysical Journal Letters, 2023 We explore terrestrial planet formation with a focus on the supply of solid-state organics as the main source of volatile carbon. For the water-poor Earth, the water ice line, or ice sublimation front, within the planet-forming disk has long been a key ...
