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…
JWST reveals anomalously enhanced methane outgassing from below Chiron's water ice and carbon dioxide bearing surface
Ian Wong, Silvia Protopapa, Aurélie Guilbert-Lepoutre +7
Centaurs are inward-scattered Kuiper belt objects, with some exhibiting comet-like activity. The physical mechanisms powering this activity remain poorly understood, with carbon mo…
JWST Spectroscopy of a Blue Binary Cold Classical Kuiper Belt Object
Ian Wong, Bryan J. Holler, Wesley C. Fraser +1
We present observations of two binary systems within the cold classical region of the Kuiper belt2001 XR254 and 2016 BP81obtained with the JWST Near-Infrared Spectrograph. Th…
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…
