The Response of Planetary Atmospheres to the Impact of Icy Comets III: Impact Driven Atmospheric Escape
Felix Sainsbury-Martinez, Greg Cooke, Catherine Walsh
In an Earth-analogue atmosphere, water vapour is a key carrier of hydrogen in the lower atmosphere with its transport above the tropopause controlling the atmospheric hydrogen esca…
The Oxygen Valve on Hydrogen Escape Since the Great Oxidation Event
Gregory J. Cooke, Dan R. Marsh, Catherine Walsh +2
The Great Oxidation Event (GOE) was a Myr transition circa 2.4 billion years ago that converted the Earth's anoxic atmosphere to one where molecular oxygen (O) was abunda…
The Response of Planetary Atmospheres to the Impact of Icy Comets I: Tidally-Locked exo-Earths
Felix Sainsbury-Martinez, Catherine Walsh, Greg Cooke
Impacts by rocky and icy bodies are thought to have played a key role in shaping the composition of solar system objects, including the Earth's habitability. Hence, it is likely th…
Asymmetries in the simulated ozone distribution on TRAPPIST-1e due to orography
Anand Bhongade, Daniel R Marsh, Felix Sainsbury-Martinez +1
TRAPPIST-1e is a tidally locked rocky exoplanet orbiting the habitable zone of an M dwarf star. Upcoming observations are expected to reveal new rocky exoplanets and their atmosphe…
