A 16 Myr Super-Neptune in Upper Centaurus Lupus and a Preliminary Survey of Transiting Planets in Sco-Cen with TESS
Measuring the properties of planets younger than about 50 Myr helps to test different planetary formation and evolution models. NASA’s Transiting Exoplanet Survey Satellite (TESS) has observed nearly the entire sky, including a wide range of…

New Research Sheds Light on Evolution of Lava Planets
Lava planets are rocky exoplanets that orbit so close to their host star that their dayside is hot enough to melt silicate rock.
Boukaré et al. introduce a simple theoretical framework to describe the evolution of the coupled…
