Atmospheric Escape Rates of Planets in Stellar Tidal Fields from 3-D Hydrodynamic Simulations
Ritika Sethi, Morgan MacLeod, Sarah Millholland
Thermally driven atmospheric escape, including photo-evaporation and core-powered mass-loss, plays a key role in shaping the evolution of close-in exoplanets, yet most current mode…
The Architecture of the 14 Herculis System Suggests Primordial Ejection of a Massive Planet
Tiger Lu, Sarah C. Millholland, Malena Rice +6
The 14 Herculis system hosts two super-Jupiters on eccentric, significantly misaligned orbits. This orbital architecture represents a dynamical puzzle that demands explanation. In…
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…
Direct Imaging Constraints on Binary Planets and Exomoons around Epsilon Indi A b
Matson Garza, Mary Anne Limbach, Rachel Bowens-Rubin +6
Epsilon Indi A b is a directly imaged exoplanet orbiting a nearby (3.6 pc) K-dwarf at AU. We analyze archival JWST/MIRI 15 m coronagraphic imaging…
Self-consistent Dynamical and Chaotic Tides in the REBOUNDx framework
Donald J. Liveoak, Sarah C. Millholland, Michelle Vick +1
At high eccentricities, tidal forcing excites vibrational modes within orbiting bodies known as dynamical tides. In this paper, we implement the coupled evolution of these modes wi…
Exploring Exoplanet Dynamics with JWST: Tides, Rotation, Rings, and Moons
Sarah C. Millholland, Joshua N. Winn
Although nearly 6,000 exoplanets are currently known, in most cases our knowledge is limited to a handful of the planet's orbital characteristics and bulk properties such as radius…
