Ion abundances in the plasma tail of 3I/ATLAS show that it is N2-rich
Lea Ferellec, Cyrielle Opitom, Colin Snodgrass
Interstellar objects allow us to compare the early planetary formation process in the Solar System and around other stars. The second and third interstellar objects, 2I/Borisov and…
Characterization of the Volatile Properties of 133P/Elst-Pizarro and Other Main-Belt Comets with JWST and Ground-Based Observations
Henry H. Hsieh, John W. Noonan, Michael S. P. Kelley +10
We report results from an analysis of the volatile composition and evolution of main-belt comet (MBC) 133P/Elst-Pizarro using JWST NIRSpec and NIRCam observations and ground-based…
Emerging Diversity Among the Main-Belt Comets: Insights from JWST and Ground-Based Observations of 457P/Lemmon-PANSTARRS
John W. Noonan, Henry H. Hsieh, Michael S. P. Kelley +10
We present JWST NIRSpec and NIRCam observations of 457P/Lemmon-PANSTARRS, a main-belt comet that displayed activity around its 2020 perihelion and that was observed to regain activ…
