The Case of Shrinking Planets
The authors of today’s papers investigate whether photoevaporation or core-powered mass loss is the more likely culprit for the exoplanet radius gap.

The number of super-Earths with small semimajor axis appears to decrease with the mass of the host star. How can this be, if more massive stars have more massive protoplanetary disks and thus more material to build planets from? An icy dead zone may be the answer to this riddle!
Music group or planetary system? Today’s paper confirms the existence of K2-138g, another sub-Neptune in K2’s most harmonious system
There is a low occurrence rate of exoplanets between 1.5 and 2.0 Earth radii. Today’s authors explore the density of the stellar field the planet resides in as a potential contributor to this gap.
