The Role of Magma Oceans in Maintaining Surface Water on Rocky Planets Orbiting M-Dwarfs
Earth-like planets orbiting M-dwarf stars, M-Earths, are currently the best targets to search for signatures of life. Life as we know it requires water. The habitability of M-Earths is jeopardized […]

UV Spectral Characterization of Low-Mass Stars With AstroSat UVIT for Exoplanet Applications: The Case Study of HIP 23309
Characterizing rocky exoplanet atmospheres is a key goal of exoplanet science, but interpreting such observations will require understanding the stellar UV irradiation incident on the planet from its host star.

Exoplanet LP 890-9c May Reveal Secrets About The Edge Of Habitability
How close can a rocky planet be to a star, and still sustain water and life? A recently discovered exoplanet may be key to solving that mystery.

How Do Rocky Planets Really Form?
A new theory for how rocky planets form could explain the origin of so-called “super-Earths”—a class of exoplanets a few times more massive than the Earth that are the most […]

Solubility Of Water In Peridotite Liquids And The Prevalence Of Steam Atmospheres On Rocky Planets
Atmospheres are products of time-integrated mass exchange between the surface of a planet and its interior. On Earth and other planetary bodies, magma oceans likely marked significant atmosphere-forming events, during […]
