The California-Kepler Survey. II. Precise Physical Properties of 2025 Kepler Planets and Their Host Stars

Understand

We present stellar and planetary properties for 1305 Kepler Objects of Interest (KOIs) hosting 2025 planet candidates observed as part of the California-Kepler Survey.

• We combine spectroscopic constraints, presented in Paper I, with stellar interior modeling to estimate stellar masses, radii, and ages.
• Stellar radii are typically constrained to 11%, compared to 40% when only photometric constraints are used.
• Stellar masses are constrained to 4%, and ages are constrained to 30%.
