Planet Masses, Radii, and Orbits from NASA's K2 Mission

Andrew W. Howard, Evan Sinukoff, Sarah Blunt +50

We report the masses, sizes, and orbital properties of 86 planets orbiting 55 stars observed by NASA's K2 Mission with follow-up Doppler measurements by the HIRES spectrometer at t…

The California-Kepler Survey. X. The Radius Gap as a Function of Stellar Mass, Metallicity, and Age

Erik A. Petigura, James G. Rogers, Howard Isaacson +10

In 2017, the California-Kepler Survey (CKS) published its first data release (DR1) of high-resolution optical spectra of 1305 planet hosts. Refined CKS planet radii revealed that s…

The California Legacy Survey I. A Catalog of 178 Planets from Precision Radial Velocity Monitoring of 719 Nearby Stars over Three Decades

Lee J. Rosenthal, Benjamin J. Fulton, Lea A. Hirsch +20

We present a high-precision radial velocity (RV) survey of 719 FGKM stars, which host 164 known exoplanets and 14 newly discovered or revised exoplanets and substellar companions.…

The California Legacy Survey II. Occurrence of Giant Planets Beyond the Ice line

Benjamin J. Fulton, Lee J. Rosenthal, Lea A. Hirsch +20

We used high-precision radial velocity measurements of FGKM stars to determine the occurrence of giant planets as a function of orbital separation spanning 0.03-30 au. Giant planet…
