The role of the Hubble Space Telescope in advancing our understanding of atmospheric escape in exoplanets
Leonardo A. Dos Santos, Arika Egan, Kevin France +14
An important evolutionary pathway for planetary atmospheres is escape to space, which has been studied on Earth and Mars for several decades and more recently in exoplanets. A part…
Modelling helium in exoplanet atmospheres. A revised network with photoelectron-driven processes
Antonio GarcÃa Muñoz
The He I line at 1.08 m is a valuable tracer of atmospheric escape in exoplanet atmospheres. We expand past networks used to predict the absorbing He(2) by including, firs…
Secondary ionisation in hot atmospheres and interactions between planetary and stellar winds
Alexandre Gillet, Antoine Strugarek, Antonio GarcÃa Muñoz
The loss of close-in planetary atmospheres is influenced by various physical processes, such as photoionisation, which could potentially affect the atmosphere survivability on a se…
Ohmic heating in the upper atmosphere of hot exoplanets The influence of a time-varying magnetic field
A. Strugarek, A. GarcÃa Muñoz, A. S. Brun +1
Exoplanets on close-in orbit are subject to intense X-ray and ultraviolet (XUV) irradiation from their star. Their atmosphere therefore heats up, sometimes to the point where it th…
