The Occurrence of Rocky Habitable Zone Planets Around Solar-Like Stars from Kepler Data

Steve Bryson, Michelle Kunimoto, Ravi K. Kopparapu +79

We present occurrence rates for rocky planets in the habitable zones (HZ) of main-sequence dwarf stars based on the Kepler DR25 planet candidate catalog and Gaia-based stellar prop…

Hubble Space Telescope Astrometry of the Metal-Poor Visual Binary Cassiopeiae: Dynamical Masses, Helium Content, and Age

Howard E. Bond, Gail H. Schaefer, Ronald L. Gilliland +1

Cassiopeiae is a nearby, high-velocity, metal-poor () visual binary. We have used high-resolution imaging with the Hubble Space Telescope (HST), obtained over…
