Page 2: Research news on Super Earths

Super-Earths as a research area encompasses the observational, theoretical, and modeling investigations of exoplanets with masses and radii larger than Earth’s but smaller than those of ice giants like Neptune. Work in this field focuses on internal structure and composition (rocky, water-rich, or volatile-dominated), atmospheric retention and chemistry under varying irradiation regimes, and formation and migration pathways in protoplanetary disks. It integrates high-precision radial-velocity and transit surveys, atmospheric spectroscopy, planetary interior modeling, and population statistics to constrain mass–radius relationships, habitability potential, and comparative planetology frameworks for understanding planetary diversity.

Second exoplanet found orbiting nearby star Gliese 536

Using radial velocity measurements, an international team of astronomers has identified a second planet orbiting a nearby M-dwarf star known as Gliese 536. The newfound alien world turns out to be at least a few times more ...

Two exoplanets discovered orbiting sun-like star

An international team of astronomers reports the discovery of two new exoplanets, a few times more massive than Earth, orbiting a sun-like star known as HD 35843. The finding was reported in a research paper published May ...

Super-Earths are common outside the solar system, new study shows

An international team including astronomers from the Center for Astrophysics | Harvard & Smithsonian (CfA) has announced the discovery of a planet about twice the size of Earth orbiting its star farther out than Saturn is ...
