Tracking the evolution of sub-Neptunes. II. The radius valley on gyrochronological ages
N. Greco, Nino Greco, Alessandro C. Lanzafame +9
The radius valley separating super-Earths from sub-Neptunes is understood as a signature of atmospheric mass loss, but the timescale over which it develops remains poorly constrain…

Tracking the evolution of sub-Neptunes. I. Gyrochronology of planet hosting stars
Alessandro C. Lanzafame, Vincenzo Drago, Nino Greco +3
Stellar age is fundamental for reconstructing planetary-system evolution but remains difficult to determine for unevolved main-sequence stars. Stellar rotation provides a sensitive…
