Thermal And Rotational Effects Of Giant Impacts During Terrestrial Planet Accretion
Terrestrial planets likely experienced one or more giant impacts during their formation that inflicted large thermal, chemical, and rotational perturbations.

Rocky Planets Orbiting Small Stars Could Have Stable Atmospheres Needed To Support Life
Since its launch in late 2021, NASA’s James Webb Space Telescope has raised the possibility that we could detect signs of life on exoplanets, or planets outside our solar system.

Coupled Geophysical And Thermal Constraints Link Between Mars Basal Molten Layer And The Planet Viscosity Profile
Computing the tidal deformations of Mars, we explored various Mars internal structures by examining profiles that include or exclude a basal molten layer within the mantle and a solid inner […]
