A Fading Radius Valley Towards M-dwarfs, A Persistent Density Valley Across Stellar Types
The radius valley separating super-Earths from mini-Neptunes is a fundamental benchmark for theories of planet formation and evolution. Observations show that the location of the radius valley decreases with decreasing […]
