The 3D Direct Simulation Monte Carlo Study of Europa’s Gas Plume
Universe, 2022 Europa has been spotted as having water outgassing activities by space- and ground-based telescopes as well as reanalysis of the Galileo data. We adopt a 3D Direct Simulation Monte Carlo (DSMC) model to investigate the observed plume characteristics of ...

Large planets may not form fractionally large moons
Nature Communications, 2022 This study finds that the Moon accreted from an initially liquid-rich silicate disk and that rocky and icy exoplanets whose radii are smaller than 1.6 Earth radii are ideal candidates for hosting large exomoons.

Prospects for Cryovolcanic Activity on Cold Ocean Planets
The Astrophysical Journal, 2023 We have estimated total internal heating rates and depths to possible subsurface oceans for 17 planets that may be cold ocean planets, low-mass exoplanets with equilibrium surface temperatures and/or densities that are consistent with icy surfaces and a ...
