Ground-Based Radial Velocity as Critical Support for Future NASA Earth-Finding Missions
Abstract
A precursor radial velocity (RV) survey would benefit direct imaging missions by (1) finding potentially habitable planets; (2) improving scheduling efficiency; (3) revealing massive planets that could be mistaken for Earth-mass planets; (4) providing the surface gravities necessary for interpreting atmospheric spectra and potential biosignatures.
