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…

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/…
