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…
Coupled Planetary Interior and Tidal Evolution
Tim Hallatt, Sarah Millholland
We present a new planetary structure/thermal evolution model, designed for use in problems that couple orbital dynamics with planetary structure. We first benchmark our structural/…
Shedding Light on Desert Dwellers
Tim Hallatt, Sarah Millholland
The ``sub-Jovian desert" (, periods 3 days) is sparsely populated but no longer empty. Recent surveys have revealed that pl…
On the Formation of Planets in the Milky Way's Thick Disk
Tim Hallatt, Eve J. Lee
Exoplanet demographic surveys have revealed that close-in (1 au) small planets orbiting stars in the Milky Way's thick disk are less abundant than those or…
