Disentangling Metallicity Effects in Hot Jupiter Occurrence Across Galactic Birth Radius and Phase-Space Density
Rayna Rampalli, Melissa K. Ness, Elisabeth R. Newton +3
We explore how the correlation between host star metallicity and giant planets shapes hot Jupiter occurrence as a function of Galactic birth radius (\rbirth) and phase-space densit…

Bar-spiral interaction produces radial migration and star formation bursts
Léa Marques, Ivan Minchev, Bridget Ratcliffe +8
Central bars and spirals are known to strongly impact the evolution of their host galaxies, both in terms of dynamics and star formation. Their typically different pattern speeds c…
