The detection of exoplanets orbiting other stars has revolutionized our view of the cosmos.
First results suggest that it is teeming with a fascinating diversity of rocky planets, including …

Exoplanet hunting efforts have revealed the prevalence of exotic worlds with diverse
properties, including Earth-sized bodies, which has fueled our endeavor to search for life …

The abundances of main carbon-and oxygen-bearing gases in the atmospheres of giant
exoplanets provide insights into atmospheric chemistry and planet formation processes …

Helium is the second-most abundant element in the Universe after hydrogen and is one of
the main constituents of gas-giant planets in our Solar System. Early theoretical models …

The search for life in the Universe is a fundamental problem of astrobiology and modern
science. The current progress in the detection of terrestrial-type exoplanets has opened a …

We present an update of the open-source photochemical kinetics code VULCAN to include
C–H–N–O–S networks and photochemistry. The additional new features are advection …

Observational evidence for esca** exoplanet atmospheres has been obtained for a few
exoplanets to date. It comes from strong transit signals detected in the ultraviolet, most …

GJ 3470b is a warm Neptune transiting an M-dwarf star at the edge of the evaporation
desert. It offers the possibility of investigating how low-mass, close-in exoplanets evolve …

Transit surveys indicate that there is a deficit of Neptune-sized planets on close-in orbits. If
this" Neptune desert" is entirely cleared out by atmospheric mass loss, then planets at its …

Atmospheres of exoplanets in the habitable zones around active young GKM stars are
subject to extreme X-ray and EUV (XUV) fluxes from their host stars that can initiate …
