The Coma Dust of Comet C2013 US10 (Catalina) A Window into Carbon in the Solar System

Comet C/2013 US10 (Catalina) was an dynamically new Oort cloud comet whose apparition presented a favorable geometry for observations near close Earth approach (~0.93au) at heliocentric distances ~2au when insolation and sublimation of volatiles drive maximum activity. Here we present mid-infrared spectrophotometric observations at two temporal epochs from NASA's Stratospheric... Show more
