JWST and Gemini Observations of the Active Centaur 450P/LONEOS: Nucleus and Coma Characterizations
Charles A. Schambeau, Michael S. P. Kelley, Maria Womack +16
Between 2019 and 2024, we used the Gemini-N and JWST observatories to conduct a detailed case study of the active Centaur 450P/LONEOS, whose orbit was significantly altered by a cl…
Astrometric follow-up of near-Earth asteroid 2024 YR4 during a Torino scale level 3 alert
Marco Micheli, Maxime Devogèle, Larry Denneau +38
The discovery of 2024 YR4 presented the planetary defense community with the most significant impact threat in almost two decades, reaching level 3 on the Torino scale. The communi…
First detection of CO emission in a Centaur: JWST NIRSpec observations of 39P/Oterma
O. Harrington Pinto, M. S. P. Kelley, G. L. Villanueva +9
Centaurs are minor solar system bodies with orbits transitioning between those of Trans-Neptunian Scattered Disk objects and Jupiter Family comets. 39P/Oterma is a frequently activ…
The LCO Outbursting Objects Key Project: Overview and Year 1 Status
Tim Lister, Michael S. P. Kelley, Carrie E. Holt +32
The LCO Outbursting Objects Key (LOOK) Project uses the telescopes of the Las Cumbres Observatory (LCO) Network to: (1) to systematically monitor a sample of Dynamically New Comets…
Establishing Earth's Minimoon Population through Characterization of Asteroid 2020 CD
Grigori Fedorets, Marco Micheli, Robert Jedicke +20
We report on our detailed characterization of Earth's second known temporary natural satellite, or minimoon, asteroid 2020 CD3. An artificial origin can be ruled out based on its a…
Contemporaneous Multi-Wavelength and Precovery Observations of Active Centaur P/2019 LD2 (ATLAS
Theodore Kareta, Laura M. Woodney, Charles Schambeau +10
Gateway Centaur and Jupiter co-orbital P/2019 LD2 (ATLAS) (Sarid et al. 2019) provides the first opportunity to observe the migration of a Solar System small body from a Centaur or…
The visual lightcurve of comet C/1995 O1 (Hale-Bopp) from 1995-1999
M. Womack, O. Curtis, D. A. Rabson +22
The long-term brightness evolution of the great comet C/1995 O1 (Hale-Bopp) presented a remarkable opportunity to study the behavior of its coma over four years. We used approximat…
CO gas and dust outbursts from Centaur 29P/Schwassmann-Wachmann
Kacper Wierzchos, Maria Womack
29P/Schwassmann Wachmann is an unusual solar system object. Originally classified as a short-period comet, it is now known as a Centaur that recently transferred to its current orb…
The Peculiar Volatile Composition of CO-Dominated Comet C/2016 R2 (PanSTARRS)
Adam McKay, Michael DiSanti, Michael Kelley +14
Comet C/2016 R2 (PanSTARRS) has a peculiar volatile composition, with CO being the dominant volatile as opposed to HO and one of the largest N/CO ratios ever observed in a…
C/2016 R2 (PANSTARRS): A comet rich in CO and depleted in HCN
Kacper Wierzchos, Maria Womack
We observed comet C/2016 R2 (PANSTARRS) with the ARO 10-m SMT, and report the first detection of CO emission from this comet with amounts high enough to be the primary driver of ac…
