Signatures of Atmospheric Mass Loss and Planet Migration in the Time Evolution of Short-Period Transiting Exoplanets

Rachel B. Fernandes, Galen J. Bergsten, Gijs D. Mulders +19

Comparative studies of young and old exoplanet populations offer a glimpse into how planets may form and evolve with time. We present an occurrence rate study of short-period (1…

The miscibility of hydrogen and water in planetary atmospheres and interiors

Akash Gupta, Lars Stixrude, Hilke E. Schlichting

Many planets in the solar system and across the galaxy have hydrogen-rich atmospheres overlying more heavy element-rich interiors with which they interact for billions of years. At…

Properties of the radius valley around low mass stars: Predictions from the core-powered mass-loss mechanism

Akash Gupta, Lorraine Nicholson, Hilke E. Schlichting

In recent years, analyzing the bimodality in the size distribution of small planets, i.e., the `radius valley', has given us unprecedented insight into the planet formation process…

The fundamentals of Lyman-alpha exoplanet transits

James E. Owen, Ruth A. Murray-Clay, Ethan Schreyer +7

Lyman- transits have been detected from several nearby exoplanets and are one of our best insights into the atmospheric escape process. However, due to ISM absorption, we typica…

Photoevaporation vs. core-powered mass-loss: model comparison with the 3D radius gap

James G. Rogers, Akash Gupta, James E. Owen +1

The EUV/X-ray photoevaporation and core-powered mass-loss models are both capable of reproducing the bimodality in the sizes of small, close-in exoplanets observed by the \textit{K…

Caught in the Act: Core-powered Mass-loss Predictions for Observing Atmospheric Escape

Akash Gupta, Hilke E. Schlichting

Past studies have demonstrated that atmospheric escape by the core-powered mass-loss mechanism can explain a multitude of observations associated with the radius valley that separa…
