A Short History of (Orbital) Decay: Roman’s Prospects for Detecting Dying Planets
The Roman Space Telescope Galactic Bulge Time Domain Survey (GBTDS) is expected to detect ∼105 transiting planets. Many of these planets will have short orbital periods and are thus susceptible to tidal decay. We use a catalog of simulated…
