Zonally and temporally averaged zonal wind profiles for both our model with the sub-stellar point placed over the ocean (SSPO - left) and sub-stellar point placed over land/Africa (SSPL - right). Here eastwards winds are shown in shades of blue whilst westwards winds are shown in shades of red. -- astro-ph.EP

How Land-Mass Distribution Influences the Atmospheric Dynamics of Tidally Locked Terrestrial Exoplanets

by Keith CowingJuly 14, 2024July 7, 2024

Interpretation of the ongoing efforts to simulate the atmospheres of potentially-habitable terrestrial exoplanets requires that we understand the underlying dynamics and chemistry of such objects to a much greater degree […]

Horizontal slices of the O3 number density for our TRAPPIST-1e model at a pressure (altitude) of a) 103 hPa (∼15 km) and b) 609 hPa (∼5 km). The substellar point is at 180° longitude and 0° latitude. N represents the North pole and S represents the South pole. Lower panels show the polar projections. -- astro-ph.EP

Asymmetries In The Simulated Ozone Distribution On TRAPPIST-1e Due To Orography

by Keith CowingJuly 6, 2024July 6, 2024

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 atmospheres around M […]
