The Discovery and Follow-up of Four Transiting Short-period Sub-Neptunes Orbiting M dwarfs

Sub-Neptunes with 2-3R_\oplus are intermediate in size between rocky planets and Neptune-sized planets. The orbital properties and bulk compositions of transiting sub-Neptunes provide clues to the formation and evolution of close-in small planets. In this paper, we present the discovery and follow-up of four sub-Neptunes orbiting M dwarfs (TOI-782, TOI-1448,... Show more
