The Influence of 10 Unique Chemical Elements in Shaping the Distribution of Kepler Planets
Robert F. Wilson, Caleb I. Cañas, Steven R. Majewski +15
The chemical abundances of planet-hosting stars offer a glimpse into the composition of planet-forming environments. To further understand this connection, we make the first ever m…
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…
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…
Elemental Abundances of Kepler Objects of Interest in APOGEE. I. Two Distinct Orbital Period Regimes Inferred from Host Star Iron Abundances
Robert F. Wilson, Johanna Teske, Steven R. Majewski +13
The Apache Point Observatory Galactic Evolution Experiment (APOGEE) has observed 600 transiting exoplanets and exoplanet candidates from \textit{Kepler} (Kepler Objects of In…
The APOGEE Spectroscopic Survey of Kepler Planet Hosts: Feasibility, Efficiency, and First Results
Scott W. Fleming, Suvrath Mahadevan, Rohit Deshpande +33
The Kepler mission has yielded a large number of planet candidates from among the Kepler Objects of Interest (KOIs), but spectroscopic follow-up of these relatively faint stars is…
Abundance Differences Between Exoplanet Binary Host Stars XO-2N and XO-2S -- Dependence on Stellar Parameters
Johanna K. Teske, Luan Ghezzi, Katia Cunha +3
The chemical composition of exoplanet host stars is an important factor in understanding the formation and characteristics of their orbiting planets. The best example of this to da…
The Homogeneous Study of Transiting Systems (HoSTS) I. The Pilot Study of WASP-13
Y. Gómez Maqueo Chew, F. Faedi, P. Cargile +13
We present the fundamental stellar and planetary properties of the transiting planetary system WASP-13 within the framework of the Homogeneous Study of Transiting Systems (HoSTS).…
