Helium in Exoplanet Exospheres: Orbital and Stellar Influences

The Astronomical Journal
Searches for helium in the exospheres of exoplanets via the metastable near-infrared triplet have yielded 17 detections and 40 nondetections. We performed a comprehensive reanalysis of published studies to investigate the influence of stellar X-ray and ...

Atmospheric Escape From Three Terrestrial Planets in the L 98-59 System

The Astrophysical Journal
A critically important process affecting the climate evolution and potential habitability of an exoplanet is atmospheric escape, in which high-energy radiation from a star drives the escape of hydrogen atoms and other light elements from a planet’s ...

Oxidizing ExoCAM: Introducing the Radiative Effects of Oxygen and Ozone into the ExoCAM General Circulation Model

The Planetary Science Journal
Oxygen and ozone are two of the most important gases in Earth’s atmosphere. These arose as a result of photosynthesis and appeared prominently around 2.3–2.4 billion yr ago.

Planetary atmospheres Through Time: Effects of Mass Loss and Thermal Evolution [PDF]

arXiv
Atmospheric mass loss is a fundamental phenomenon shaping the structure and evolution of planetary atmospheres. It can engage processes ranging from global interactions with the host star and large-scale hydrodynamic outflows to essentially microphysical kinetic effects.
