Overfitting Affects the Reliability of Radial Velocity Mass Estimates of the V1298 Tau Planets
Sarah Blunt, Adolfo Carvalho, Trevor J. David +23
Mass, radius, and age measurements of young (<100 Myr) planets have the power to shape our understanding of planet formation. However, young stars tend to be extremely variable in…
The TESS-Keck Survey. XVI. Mass Measurements for 12 Planets in Eight Systems
Joseph M. Akana Murphy, Natalie M. Batalha, Nicholas Scarsdale +44
With JWST's successful deployment and unexpectedly high fuel reserves, measuring the masses of sub-Neptunes transiting bright, nearby stars will soon become the bottleneck for char…
