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.

Exoplanet atmosphere evolution: emulation with neural networks
Monthly 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.

Interpreting exoplanet biosignatures with a coupled atmosphere-interior-geochemical evolution model
2021<p>The atmospheric evolution of rocky planets is shaped by a range of astrophysical, geophysical, and geochemical processes. Interpreting observations of potentially habitable exoplanets will require an improved understanding of how these competing influences interact on long timescales.

Monthly Notices of the Royal Astronomical SocietyABSTRACT Understanding how exoplanet atmospheres evolve is a key question in the context of habitability. One key process governing this evolution is atmospheric evaporation by stellar X-ray and EUV (extreme ultraviolet) emission (collectively, XUV).

Interior structure, mantle-atmosphere co-evolution, and habitability of low-mass exoplanets
2023Um grundlegende Fragen der Planetenforschung zu beantworten, ist ein fundiertes Verständnis der Zusammensetzung und der Prozesse im Inneren von Exoplaneten eine essenzielle Voraussetzung. Solche Fragen beinhalten beispielsweise, welche Arten von Planeten es geben könnte, welche Mechanismen die Planetenentstehung und -entwicklung steuern, wie ...

Haze Evolution in Temperate Exoplanet Atmospheres: the Laboratory Perspective
2022With thousands of confirmed detections of exoplanets, recent efforts are focusing on characterizing their atmospheres through transmission spectroscopy. However, opacity sources such as condensation clouds and photochemical hazes have been found to be common in exoplanet atmospheres, muting spectroscopic features of atmospheric species.

Coupling the Atmospheric and Dynamical Evolution of Close-in Exoplanets
The vast majority of the detected exoplanets orbit in less than a month around their star, in extreme conditions unmet in the Solar System. The demographics of these close-in planets exhibit a striking feature: the lack of Neptune-size worlds on very short orbits, also dubbed the "Neptunian desert", which challenges our understanding of planetary ...Omar Attia, Vincent Bourrier

Exodus: A mission proposal to explore exoplanet evolution through understanding atmospheric escape
Advances in Space ResearchUnderstanding the variety of system architectures and formation histories of planetary systems remains a major challenge. Current detection methods are strongly biased towards short-period bodies, leaving a gap in the exoplanet population demographics.
