“Cold Neptune” and two temperate super-Earths found orbiting nearby stars

An artist’s concept of GJ180d, which is the nearest temperate super-Earth to us that is not tidally locked to its star, making it more likely to be able to host and sustain life. Illustration is by Robin Dienel, courtesy of the Carnegie Institution for Sc

A “cold Neptune” and two potentially habitable worlds are part of a cache of five newly discovered exoplanets and eight exoplanet candidates found orbiting nearby red dwarf stars, which are reported in The Astrophysical Journal Supplement Series by a team led by Carnegie’s Fabo Feng and Paul Butler.
