Prospects For Water Vapor Detection In The Atmospheres Of Temperate And Arid Rocky Exoplanets Around M-dwarf Stars
Detection of water vapor in the atmosphere of temperate rocky exoplanets would be a major milestone on the path towards characterization of exoplanet habitability. Past modeling work has shown that […]
