The Response of Planetary Atmospheres to the Impact of Icy Comets I: Tidally-Locked exo-Earths

by Keith CowingNovember 29, 2024November 29, 2024

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 […]

Zonally and temporally averaged snow fraction for our reference non-impacted model (top left) and at three points in time post-impact for our combined water and heat deposition impact model: 6 months post-impact (top right), 1 year post-impact (bottom left), and 15 years post-impact (bottom right), by which time the impacted models snow fraction has returned to a state clost to that found in our non-impacted reference state. -- astro-ph.EP
