Evidence for a Volcanic Atmosphere on the Sub-Earth L 98-59 b

Evidence for a Volcanic Atmosphere on the Sub-Earth L 98-59 b

Assessing the prevalence of atmospheres on rocky planets around M-dwarf stars is a top priority of exoplanet science. High-energy activity from M dwarfs can destroy the atmospheres of these planets, which could explain the lack of atmosphere detections to date. Volcanic outgassing has been proposed...
