A Dormant Captured Oort Cloud Comet Awakens: (18916) 2000 OG44
Colin Orion Chandler, William J. Oldroyd, Chadwick A. Trujillo +2
We report the discovery of activity emanating from (18916) 2000 OG44 (alternately designated 1977 SD), a minor planet previously reported to be both an extinct comet or an asteroid…
Recurrent Cometary Activity Discovered on Quasi-Hilda Jupiter Family Comet 362P/(457175) 2008 GO98
Kennedy A. Farrell, Colin Orion Chandler, Chadwick A. Trujillo +5
We report the discovery of recurrent activity on quasi-Hilda comet (QHC) 362P/(457175) 2008 GO98. The first activity epoch was discovered during the perihelion passage of 362P. The…
Evaluating an Embryo Origin for Detached TNOs within Full Kuiper Belt Formation Models
Nathan A. Kaib, Chadwick A. Trujillo, Scott S. Sheppard
With perihelia well beyond Neptune, but semimajor axes and eccentricities indicative of substantial perturbation, the origins of detached trans-Neptunian objects (TNOs) remain a dy…
NSF-DOE Vera C. Rubin Observatory Observations of Interstellar Comet 3I/ATLAS (C/2025 N1)
Colin Orion Chandler, Pedro H. Bernardinelli, Mario Jurić +305
We report on the observation and measurement of astrometry, photometry, morphology, and activityof the interstellar object 3I/ATLAS, also designated C/2025 N1 (ATLAS) with the NSF-…
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…
New Moons of Uranus and Neptune from Ultra-Deep Pencil Beam Surveys
Scott Sheppard, David Tholen, Marina Brozovic +4
We have conducted extremely ultra-deep pencil beam observations for new satellites around both Uranus and Neptune. Tens of images on several different nights in 2021, 2022 and 2023…
