Theoretical determination of the binding energies of methanol and related species onto amorphous solid water ice
Aneesa Ahmad, Catherine Walsh, Stefan Vogt-Geisse +2
The formation and survival of complex organic molecules (COMs) in cold interstellar environments depends on their interactions with icy dust grain surfaces. Methanol, a key COM det…
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 II: exo-Earth Analogues
F. Sainsbury-Martinez, C. Walsh
The orbital regime of a terrestrial planet plays a significant role in shaping its atmospheric dynamics, climate, and hence potential habitability. The orbit is also likely to play…
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…
