SPORES-HWO. II. Limits on Planetary Companions of Future High-contrast Imaging Targets from >20 Years of HIRES and HARPS Radial Velocities

Future large, space-based observatories with starlight suppression technology, e.g., the Habitable Worlds Observatory (HWO), will directly image and characterize nearby Earth-like exoplanets. Prior limits on planet masses and system architectures from radial velocity (RV) measurements of potential exo-Earth hosts are critical to the success of HWO's science goals. Here, we... Show more
