An Increase in the Galactic Planet Host Fraction Fails to Reproduce the Galactic Height Trend in Planet Occurrence
Christopher Lam, Sarah Ballard, Sheila Sagear +1
While stellar metallicity has long been known to correlate with planetary properties, the galactic metallicity gradient alone does not account for the observed strong trend in plan…

The Orbital Eccentricities of Planets in the Kinematic Thin and Thick Galactic Disks
Sheila Sagear, Sarah Ballard, Kathryne J. Daniel +4
The orbital eccentricity distribution of exoplanets is shaped by a combination of dynamical processes, reflecting both formation conditions and long-term evolution. Probing the orb…

The Orbital Eccentricity-Radius Relation for Planets Orbiting M Dwarfs
Sheila Sagear, Sarah Ballard, Gregory J. Gilbert +2
The orbital eccentricity-radius relation for small planets is indicative of the predominant dynamical sculpting processes during late-stage orbital evolution. Previous studies have…
