Improved Constraints on the Surface of LHS 3844 b from its Mid-Infrared Spectrum

Kimberly Paragas, Heather A. Knutson, Renyu Hu +4

The thermal emission spectra of terrestrial exoplanets provide a window into their surface compositions and corresponding geological processes. Close-in, rocky planets orbiting M d…

A New Spectral Library for Modeling the Surfaces of Hot, Rocky Exoplanets

Kimberly Paragas, Heather A. Knutson, Renyu Hu +7

JWST's MIRI LRS provides the first opportunity to spectroscopically characterize the surface compositions of close-in terrestrial exoplanets. Models for the bare-rock spectra of th…

Detection of a 2.85 micrometer Feature on 5 Spinel-rich Asteroids from JWST

Jonathan Gomez Barrientos, Katherine de Kleer, Bethany L. Ehlmann +2

Ground-based observations of `Barbarian' L-type asteroids at 1 to 2.5-m indicate that their near-infrared spectra are dominated by the mineral spinel, which has been attributed…

Venus Life Finder Mission Study

Sara Seager, Janusz J. Petkowski, Christopher E. Carr +9

The Venus Life Finder Missions are a series of focused astrobiology mission concepts to search for habitability, signs of life, and life itself in the Venus atmosphere. While peopl…
