One of the primary questions when characterizing Earth-sized and super-Earth-sized exoplanets is whether they have a substantial atmosphere like Earth and Venus or a bare-rock surface like Mercury. Phase curves […]

A Super-Earth on the Inner Edge of the Habitable Zone of the Nearby M-dwarf GJ 625
We report the discovery of a super-Earth orbiting at the inner edge of the habitable zone of the star GJ 625 based on the analysis of the radial-velocity (RV) time […]

A Temperate Rocky Super-Earth Transiting a Nearby Cool Star
M dwarf stars, which have masses less than 60 per cent that of the Sun, make up 75 per cent of the population of the stars in the Galaxy [1]. […]

The Formation and Chemical Composition of Super Earths
Super Earths are the largest population of exoplanets and are seen to exhibit a rich diversity of compositions as inferred through their mean densities. Here we present a model that […]

Formation of Close in Super-Earths and Mini-Neptunes
Recent observations by the Kepler space telescope have led to the discovery of more than 4000 exoplanet candidates consisting of many systems with Earth- to Neptune-sized objects that reside well […]

Terrestrial Planet Formation in the Presence of Migrating Super-earths
Super-Earths with orbital periods less than 100 days are extremely abundant around Sun-like stars. It is unlikely that these planets formed at their current locations. Rather, they likely formed at […]

Hubble Near-IR Transmission Spectroscopy of the Super-Earth HD 9765
Recent results from the Kepler mission indicate that super-Earths (planets with masses between 1-10 times that of the Earth) are the most common kind of planet around nearby Sun-like stars. […]
