Sub-Neptunes are high-occurrence exoplanets that have no solar system analog. Much smaller than gas giants and typically cooler than hot-Jupiter exoplanets,...
Water is an important component of exoplanets, with its distribution, that is, whether at the surface or deep inside, fundamentally influencing the planetary...
Created as part of the TESS-Keck Survey, the new catalog includes 126 strange planets beyond our Solar System, from rare worlds with extreme environments...
