A Spectroscopic Analysis of the California-Kepler Survey Sample: II. Correlations of Stellar Metallicities with Planetary Architectures
Luan Ghezzi, Cintia F. Martinez, Robert F. Wilson +3
We present independent and self-consistent metallicities for a sample of 807 planet-hosting stars from the California-Kepler Survey from an LTE spectroscopic analysis using a selec…
Emerging trends in metallicity and lithium properties of debris disc stars
C. Chavero, R. de la Reza, L. Ghezzi +5
Dwarf stars with debris discs and planets appear to be excellent laboratories to study the core accretion theory of planets formation. These systems are however, insufficiently stu…
A Spectroscopic Analysis of the California-Kepler Survey Sample: I. Stellar Parameters, Planetary Radii and a Slope in the Radius Gap
Cintia F. Martinez, Katia Cunha, Luan Ghezzi +1
We present results from a quantitative spectroscopic analysis conducted on archival Keck/HIRES high-resolution spectra from the California- Survey (CKS) sample of transitin…
Retired A Stars Revisited: An Updated Giant Planet Occurrence Rate as a Function of Stellar Metallicity and Mass
Luan Ghezzi, Benjamin T. Montet, John Asher Johnson
Exoplanet surveys of evolved stars have provided increasing evidence that the formation of giant planets depends not only on stellar metallicity ([Fe/H]), but also the mass ($M_\st…
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 M. This deficit, know…
