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…
A coupled model of episodic warming, oxidation and geochemical transitions on early Mars
Robin Wordsworth, Andrew H. Knoll, Joel Hurowitz +4
Reconciling the geology of Mars with models of atmospheric evolution remains a major challenge. Martian geology is characterized by past evidence for episodic surface liquid water,…
In Situ Geochronology for the Next Decade: Mission Designs for the Moon, Mars, and Vesta
Barbara A. Cohen, Kelsey E. Young, Nicolle E. B. Zellner +27
Geochronology, or determination of absolute ages for geologic events, underpins many inquiries into the formation and evolution of planets and our Solar System. Absolute ages of an…
A probabilistic approach to determination of Ceres' average surface composition from Dawn VIR and GRaND data
H. Kurokawa, B. L. Ehlmann, M. C. De Sanctis +6
The Visible-Infrared Mapping Spectrometer (VIR) on board the Dawn spacecraft revealed that aqueous secondary minerals -- Mg-phyllosilicates, NH4-bearing phases, and Mg/Ca carbonate…
Hubble Ultraviolet Spectroscopy of Jupiter Trojans
Ian Wong, Michael E. Brown, Jordana Blacksberg +2
We present the first ultraviolet spectra of Jupiter Trojans. These observations were carried out using the Space Telescope Imaging Spectrograph on the Hubble Space Telescope and co…
