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…
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…
Uncovering the Rapidly Evolving Orbits of the Dynamic TOI-201 System
Ismael Mireles, Solène Ulmer-Moll, Donald Liveoak +47
Studying planetary interactions in exoplanet systems informs theories of planet formation and evolution, providing essential context for understanding our own solar system. We comb…
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…
