An Earth-sized Planet on the Verge of Tidal Disruption
Fei Dai, Andrew W. Howard, Samuel Halverson +95
TOI-6255~b (GJ 4256) is an Earth-sized planet (1.079 ) with an orbital period of only 5.7 hours. With the newly commissioned Keck Planet Finder (KPF) and CARMEN…
New insights into the internal structure of GJ 1214 b informed by JWST
Matthew C. Nixon, Anjali A. A. Piette, Eliza M. -R. Kempton +7
Recent JWST observations of the sub-Neptune GJ 1214 b suggest that it hosts a high-metallicity (>100x solar), hazy atmosphere. Emission spectra of the planet show molecular absorpt…
Helium Enhanced Planets Along the Upper Edge of the Radius Valley
Isaac Malsky, Leslie Rogers, Eliza M. R. Kempton +1
The low mean densities of sub-Neptunes imply that they formed within a few million years and accreted primordial envelopes. Because these planets receive a total X-ray and extreme…
Where are the Water Worlds?: Self-Consistent Models of Water-Rich Exoplanet Atmospheres
Eliza M. -R. Kempton, Madeline Lessard, Matej Malik +5
It remains to be ascertained whether sub-Neptune exoplanets primarily possess hydrogen-rich atmospheres or whether a population of HO-rich "water worlds" lurks in their midst.…
Mass Upper Bounds for Over 50 Kepler Planets Using Low-S/N Transit Timing Variations
Jared C. Siegel, Leslie A. Rogers
Prospects for expanding the available mass measurements of the Kepler sample are limited. Planet masses have typically been inferred via radial velocity (RV) measurements of the ho…
Thermal Evolution and magnetic history of rocky planets
Jisheng Zhang, Leslie Rogers
We present a thermal evolution model coupled with a Henyey solver to study the circumstances under which a rocky planet could potentially host a dynamo in its liquid iron core and/…
