The Neptunian Final Parsec Problem: How Inertial Waves Enable Neptunes and Gas Giants to Survive Tidal Migration
Tim Hallatt, Adrian J. Barker, Sarah C. Millholland
Observations indicate that some hot Neptunes and Jupiters underwent high eccentricity migration (HEM). A longstanding issue facing HEM theory remains, however: in order to shrink t…
Coupled Orbital and Interior Evolution of Sub-Neptunes
Ritika Sethi, Sarah Millholland, Tim Hallatt
Recent observations have yielded the first measurements of young exoplanet demographics. Close-in sub-Neptune occurrence rates appear to rise from young ( Myr) to intermedi…
Shaving the Outskirts of Planetary Systems Probed by Roman via Stellar Flybys
Donald Liveoak, Tim Hallatt, Sarah Millholland
The recently launched Nancy Grace Roman Space Telescope (\textit{Roman}) will soon begin observations that promise to revolutionize our understanding of exoplanet demographics. \te…
Case Study of a Super-eccentric Warm Jupiter Migrating via Equilibrium and Dynamical Tides
Donald Liveoak, Sarah Millholland, Michelle Vick
A leading theory for hot Jupiter formation is high-eccentricity migration, in which planets are born at large separations and excited to near-unity eccentricities, creating extreme…
Revealing the Origin of Desert Dwellers via Stellar Obliquities
Tim Hallatt, James E. Owen, Sarah Millholland
Observations suggest that the hot Neptune desert contains the remnants of destroyed gas giants. Recent theoretical work has shown that gas giant destruction via Roche lobe overflow…
Stability of Multiplanet Systems Through Hot Jupiter Destruction
Donald Liveoak, Tim Hallatt, Sarah Millholland
Recent observational and theoretical work suggests that the sub-Jovian desert (periods days, masses ) hosts the remains of destroyed hot…
Resonant sub-Neptunes are puffier
Adrien Leleu, Jean-Baptiste Delisle, Remo Burn +12
A systematic, population-level discrepancy exists between the densities of exoplanets whose masses have been measured with transit timing variations (TTVs) versus those measured wi…
