A New Window into Planet Formation and Migration: Refractory-to-Volatile Elemental Ratios in Ultra-hot Jupiters
Joshua D. Lothringer, Zafar Rustamkulov, David K. Sing +3
A primary goal of exoplanet characterization is to use a planet's current composition to understand how that planet formed. For example, the C/O ratio has long been recognized as c…
The non-monotonic, strong metallicity dependence of the wide-binary fraction
Hsiang-Chih Hwang, Yuan-Sen Ting, Kevin C. Schlaufman +2
The metallicity dependence of the wide-binary fraction in stellar populations plays a critical role in resolving the open question of wide binary formation. In this paper, we inves…
An Increase in Small-planet Occurrence with Metallicity for Late-type Dwarf Stars in the Kepler Field and Its Implications for Planet Formation
Cicero X. Lu, Kevin C. Schlaufman, Sihao Cheng
While it is well established that giant-planet occurrence rises rapidly with host star metallicity, it is not yet clear if small-planet occurrence around late-type dwarf stars depe…
The Most Metal-poor Stars in the Inner Bulge
Henrique Reggiani, Kevin C. Schlaufman, Andrew R. Casey +1
The bulge is the oldest component of the Milky Way. Since numerous simulations of Milky Way formation have predicted that the oldest stars at a given metallicity are found on tight…
Ultra-short-period Planets are Stable Against Tidal Inspiral
Jacob H. Hamer, Kevin C. Schlaufman
It has been unambiguously shown in both individual systems and at the population level that hot Jupiters experience tidal inspiral before the end of their host stars' main sequence…
Very wide companion fraction from Gaia DR2: a weak or no enhancement for hot jupiter hosts, and a strong enhancement for contact binaries
Hsiang-Chih Hwang, Jacob H. Hamer, Nadia L. Zakamska +1
There is an ongoing debate on whether hot jupiter hosts are more likely to be found in wide binaries with separations of AU. In this paper, we search for comoving, ve…
