Investigating potential causes for high inferred intrinsic temperatures of warm transiting Neptune and Sub-Neptune planets

Saugata Barat, Jean-Michel Désert, Allona Vazan +7

Atmospheric characterization of a warm 10-30 Myr old sub-Neptune progenitor (V1298 Tau b) and a 3.4 Gyr old warm super-Neptune (WASP-107b) using JWST have revealed extremely…

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…

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…

An Eccentric Sub-Neptune Moving Into the Evaporation Desert

Sydney Jenkins, Andrew Vanderburg, Ritika Sethi +31

Though missions such as Kepler, K2, and TESS have discovered 2,000 sub-Neptune and Neptunian planets, there is a dearth of such planets at close-in (P3 days) orbits. T…

Tidal Inflation is Stronger for Misaligned Neptune-Sized Planets Than Aligned Ones

Ritika Sethi, Sarah Millholland

Recent observations have revealed an intriguing abundance of polar-orbiting Neptune-sized planets, many of which exhibit unusually inflated radii. While such misaligned orbits poin…
