Constraining Ongoing Volcanic Outgassing Rates and Interior Compositions of Extrasolar Planets with Mass Measurements of Plasma Tori

We present a novel method of constraining volcanic activity on extrasolar terrestrial worlds via characterization of circumstellar plasma tori.

Atmospheric Retrievals Suggest The Presence of a Secondary Atmosphere and Possible Sulfur Species on L 98-59 d from JWST NIRSpec G395H Transmission Spectroscopy

L 98-59 d is a Super-Earth planet orbiting an M-type star. We performed retrievals on the transmission spectrum of L 98-59 d obtained using NIRSpec G395H during a single transit, […]

Assessing the Detectability of Europa’s Seafloor Topography from Europa Clipper’s Gravity Data

Due to its size and tidal heating, Europa may potentially possess active volcanism and hydrothermal circulation at its seafloor.
