Disentangling Metallicity Effects in Hot Jupiter Occurrence across Galactic Birth Radius and Phase-space Density

Disentangling Metallicity Effects in Hot Jupiter Occurrence across Galactic Birth Radius and Phase-space Density

We explore how the correlation between host star metallicity and giant planets shapes hot Jupiter occurrence as a function of Galactic birth radius ( R _birth ) and phase-space density in the Milky Way disk. Using the Galactic Archaeology with HERMES (GALAH) and Apache Point Observatory Galactic Evo...
