Disintegration of Long-period Comet C/2019 Y4 (ATLAS). II. Post-Perihelion Remnant Recovery
Salvatore A. Cordova Quijano, Quanzhi Ye, Michael S. P. Kelley
We present an investigation into the fate of disrupting near-Sun comet C/2019 Y4 (ATLAS). Imaging observations with the Lowell Discovery Telescope (LDT), obtained 3--5 months after…
A Large Outburst, Coma Asymmetries, and the Color of Comet 243P/NEAT
Michael S. P. Kelley, Silvia Protopapa, Dennis Bodewits +16
Water ice is a fundamental building material of comets and other bodies in the outer solar system. Yet, the properties of cometary water ice are challenging to study, due to its vo…
Deep learning to improve the discovery of near-Earth asteroids in the Zwicky Transient Facility
Belén Yu Irureta-Goyena, George Helou, Jean-Paul Kneib +7
We present a novel pipeline that uses a convolutional neural network (CNN) to improve the detection capability of near-Earth asteroids (NEAs) in the context of planetary defense. O…
In Search of the Potentially Hazardous Asteroids in the Taurid Resonant Swarm
Jasmine Li, Quanzhi Ye, Denis Vida +8
The Taurid Complex is a large interplanetary system that contains comet 2P/Encke, several meteoroid streams, and possibly a number of near-Earth asteroids. The size and nature of t…
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…
Observational Characterization of Main-Belt Comet and Candidate Main-Belt Comet Nuclei
Henry H. Hsieh, Marco Micheli, Michael S. P. Kelley +9
We report observations of nine MBCs or candidate MBCs, most of which were obtained when the targets were apparently inactive. We find effective nucleus radii (assuming albedos of p…
