A SUPER-SOLAR METALLICITY FOR STARS WITH HOT ROCKY EXOPLANETS
ABSTRACT Host star metallicity provides a measure of the conditions in protoplanetary disks at the time of planet formation. Using a sample of over 20,000 Kepler stars with spectroscopic metallicities from the LAMOST survey, we explore how the exoplanet population depends on host star metallicity as a function of orbital …
