The Volatile Composition and Activity Evolution of Main-Belt Comet 358P/PANSTARRS
Henry H. Hsieh, John W. Noonan, Michael S. P. Kelley +17
We report the detection of water vapor associated with main-belt comet 358P/PANSTARRS on UT 2024 January 8-9 using the NIRSPEC instrument aboard JWST. We derive a water production…
Planetary Defense Use of the SPHEREx Solar System Object Catalog
Carey Lisse, James Bauer, Yaeji Kim
The upcoming NASA SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer) all-sky 0.7 to 5.0 um spectral survey, to be conducted from…
The surface sensitivity of rubble-pile asteroids during a distant planetary encounter: Influence of asteroid shape elongation
Yaeji Kim, Masatoshi Hirabayashi, Richard P Binzel +3
We numerically investigate how an asteroid's elongation controls the sensitivity of its surface to tidal effects during a distant planetary encounter beyond the Roche limit. We ana…
JWST Characterization of Earth Quasi-Satellite (469219) Kamo`oalewa
Benjamin N. L Sharkey, Vishnu Reddy, John W. Noonan +5
Near-Earth asteroid (469219) Kamo`oalewa is a uniquely stable quasi-satellite of the Earth and a target of the Tianwen-2 spacecraft mission. Here we report observations taken with…
A numerical approach using a finite element model to constrain the possible interior layout of (16) Psyche
Yaeji Kim, Masatoshi Hirabayashi
Asteroid (16) Psyche is notable for the largest M-type asteroid and has the high radar albedo among the main-belt asteroids. The object is likely a mixture of metal and silicates b…
Active Main-Belt Asteroid (6478) Gault -- Constraint on Its Cohesive Strength and the Fate of Ejected Particles in the Solar System
Pierce M. Jackson, Ryota Nakano, Yaeji Kim +1
Active asteroid (6478) Gault sheds mass independent of location along its orbit. Rotational instability is considered to induce the observed activities. If this is the case, becaus…
