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…
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…
Impact Rates in the Outer Solar System
David Nesvorny, Luke Dones, Mario De Pra +2
Previous studies of cometary impacts in the outer Solar System used the spatial distribution of ecliptic comets (ECs) from dynamical models that assumed ECs began on low-inclinatio…
The Transition from the Kuiper Belt to the Jupiter-Family (Comets)
Wesley C. Fraser, Luke Dones, Kathryn Volk +2
Kuiper Belt Objects, or more generally Trans-Neptunian Objects (TNOs), are planetesimals found beyond the orbit of Neptune. Some TNOs evolve onto Neptune-crossing orbits and become…
29P/Schwassmann-Wachmann: A Rosetta Stone for Amorphous Water Ice and CO <-> CO2 Conversion in Centaurs and Comets?
C. M. Lisse, J. K. Steckloff, D. Prialnik +12
Centaur 29P/Schwassmann-Wachmann 1 (SW1) is a highly active object orbiting in the transitional Gateway region (Sarid et al. 2019) between the Centaur and Jupiter Family Comet regi…
Characterization of Thermal Infrared Dust Emission and Refinements to the Nucleus Properties of Centaur 29P/Schwassmann-Wachmann 1
Charles A. Schambeau, Yanga R. Fernandez, Nalin H. Samarasinha +4
We present analyses of Spitzer observations of 29P/Schwassmann-Wachmann 1 using 16 m IRS "blue" peak-up (PU) and 24 m and 70 m MIPS images obtained on UT 2003 November 23…
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…
Characterization of material around the centaur (2060) Chiron from a visible and near-infrared stellar occultation in 2011
A. A. Sickafoose, A. S. Bosh, J. P. Emery +6
The centaur (2060) Chiron has exhibited outgassing behaviour and possibly hosts a ring system. On 2011 November 29, Chiron occulted a fairly bright star (R approximately 15 mag) as…
29P/Schwassmann-Wachmann 1, A Centaur in the Gateway to the Jupiter-Family Comets
Gal Sarid, Kathryn Volk, Jordan Steckloff +3
Jupiter-family comets (JFCs) are the evolutionary products of trans-Neptunian objects (TNOs) that evolve through the giant planet region as Centaurs and into the inner solar system…
