The Dust Mineralogy of Interstellar Comet 3I/ATLAS from JWST/MIRI Observations
Matthew Belyakov, Ian Wong, Carey M. Lisse +7
We present the first spectroscopic mineralogical analysis of the dust coma of an interstellar object (ISO) from JWST mid-infrared spectroscopy of 3I/ATLAS (3I). 3I exhibits a stron…
The Volatile Inventory of 3I/ATLAS as seen with JWST/MIRI
Matthew Belyakov, Ian Wong, Bryce T. Bolin +4
We present the first spectroscopic characterization of an interstellar object at mid-infrared wavelengths. Post-perihelion observations of 3I/ATLAS using the JWST/MIRI medium-resol…
Satellites and small bodies with ALMA: Insights into Solar System formation & evolution
Katherine de Kleer, Michael E. Brown, Martin Cordiner +1
Our understanding of the formation and evolution of planetary systems has made major advances in the past decade. This progress has been driven in large part by the Atacama Large M…
JWST Near Infrared Spectroscopy of High Albedo Jupiter Trojans: A New Surface Type in the Trojan Belt
Michael E. Brown, Ian Wong, Matthew Belyakov
We present 0.8 to 5 m JWST spectra of four 20 km diameter Jupiter Trojans known to have albedos elevated above the values typical in the remaining Trojan population. The…
A JWST study of CO on the satellites of Saturn
Michael E. Brown, Samantha K. Trumbo, Matthew Belyakov +2
Solid state CO has been detected throughout the outer solar system, even at temperatures where crystalline CO is unstable, requiring that the CO be trapped in a separat…
Spectroscopic Mapping of Callisto with HST/STIS and Implications for its Surface Composition
M. Ryleigh Davis, Samantha K. Trumbo, Michael E. Brown +1
We present global, spatially resolved ultraviolet-visible spectra of Callisto obtained with HST/STIS and explore possible compositions of Callisto's surface material. We map the st…
