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…
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…
The evolutionary track of H/He envelope in the observed population of sub-Neptunes and Super-Earths planets
Raissa Estrela, Mark Swain, Akash Gupta +2
The observational detection of a localized reduction in the small planet occurrence rate, sometimes termed a 'gap', is an exciting discovery because of the implications for planet…
Signatures of the Core-Powered Mass-Loss Mechanism in the Exoplanet Population: Dependence on Stellar Properties and Observational Predictions
Akash Gupta, Hilke E. Schlichting
Recent studies have shown that atmospheric mass-loss powered by the cooling luminosity of a planet's core can explain the observed radius valley separating super-Earths and sub-Nep…
