Fine Structure of the Age-Chromospheric Activity Relation in Solar-Type Stars: II. Hα Line

Paulo V. Souza dos Santos, Gustavo F. Porto de Mello, Erica Costa-Bhering +4

Excess chromospheric emissions within deep photospheric lines are effective proxies of stellar magnetism for FGK stars. This emission decays with stellar age and is a potential det…

Chemo-kinematics of the Milky Way from the SDSS-III MARVELS Survey

Nolan Grieves, Jian Ge, Neil Thomas +20

Combining stellar atmospheric parameters, such as effective temperature, surface gravity, and metallicity, with barycentric radial velocity data provides insight into the chemo-dyn…

Exploring the Brown Dwarf Desert: New Substellar Companions from the SDSS-III MARVELS Survey

Nolan Grieves, Jian Ge, Neil Thomas +27

Planet searches using the radial velocity technique show a paucity of companions to solar-type stars within ~5 AU in the mass range of ~10 - 80 MJup​. This deficit, know…
