Multi-year Ground-Based Survey Photometry of Active Comet 103P/Hartley 2 and Centaur (2060) Chiron: A Tale of Two Comets in the Pre-LSST Era
Joseph Murtagh, Megan E. Schwamb, Michael S. P. Kelley +22
Comets and Centaurs trace the evolution of trans-Neptunian objects (TNOs) into the inner solar system. Their activity reflects the interplay between volatile sublimation, dust dyna…
On the Border: Searching for Cometary Activity Near the Centaur-JFC Transition Line
A. Fraser Gillan, Alan Fitzsimmons, Colin Orion Chandler +2
Current wide-field surveys discover ~15 Jupiter-family comets (JFCs) each year, typically identified via visual detection of a dust coma or tail. The same surveys also discover man…
ATLAS Photometry of Interstellar Object 3I/ATLAS
John Tonry, Larry Denneau, Miguel Alarcon +7
We present calibrated ATLAS photometry of the interstellar comet 3I/ATLAS (C/2025 N1) from 28 March through 29 Aug 2025, obtained with the five-site, robotic ATLAS network in the c…
Dust production rates in Jupiter-family comets II: Trends and population insights from ATLAS photometry of 116 JFCs
A. Fraser Gillan, Alan Fitzsimmons, Larry Denneau +4
Jupiter-family comets (JFCs) have orbital periods of less than 20 years and therefore undergo more frequent sublimation compared to other comet populations. The JFCs therefore repr…
Analysing the Onset of Cometary Activity by the Jupiter-Family Comet 2023 RN3
Matthew M. Dobson, Megan E. Schwamb, Alan Fitzsimmons +17
We utilize serendipitous observations from the Asteroid Terrestrial-impact Last Alert System (ATLAS) and the Zwicky Transient Facility (ZTF) in addition to targeted follow-up obser…
The Discovery and Evolution of a Possible New Epoch of Cometary Activity by the Centaur (2060) Chiron
Matthew M. Dobson, Megan E. Schwamb, Alan Fitzsimmons +24
Centaurs are small Solar System objects on chaotic orbits in the giant planet region, forming an evolutionary continuum with the Kuiper belt objects and Jupiter-family comets. Some…
Main-belt and Trojan Asteroid Phase Curves from the ATLAS Survey
James E. Robinson, Alan Fitzsimmons, David R. Young +6
Sparse and serendipitous asteroid photometry obtained by wide field surveys such as the Asteroid Terrestrial-impact Last Alert System (\ATLAS) is a valuable resource for studying t…
Dust production rates in Jupiter-family Comets: A two-year study with ATLAS photometry
A. Fraser Gillan, Alan Fitzsimmons, Larry Denneau +4
Jupiter-family Comets (JFCs) exhibit a wide range of activity levels and mass-loss over their orbits. We analyzed high-cadence observations of 42 active JFCs with the wide-field As…
The dust environment of comet 67P/Churyumov-Gerasimenko from Rosetta OSIRIS and VLT observations in the 4.5 to 2.9 au heliocentric distance range inbound
F. Moreno, C. Snodgrass, O. Hainaut +51
The ESA Rosetta spacecraft, currently orbiting around comet 67P, has already provided in situ measurements of the dust grain properties from several instruments, particularly OSIRI…
Main-Belt Comet P/2012 T1 (PANSTARRS)
Henry H. Hsieh, Heather M. Kaluna, Bojan Novakovic +25
We present initial results from observations and numerical analyses aimed at characterizing main-belt comet P/2012 T1 (PANSTARRS). Optical monitoring observations were made between…
Physical and dynamical characterisation of low Delta-V NEA (190491) 2000 FJ10
A. A. Christou, T. Kwiatkowski, M. Butkiewicz +4
We investigated the physical properties and dynamical evolution of Near Earth Asteroid (NEA) (190491) 2000 FJ10 in order to assess the suitability of this accessible NEA as a space…
Discovery of Main-Belt Comet P/2006 VW139 by Pan-STARRS1
Henry H. Hsieh, Bin Yang, Nader Haghighipour +39
Main belt asteroid (300163) 2006 VW139 (later designated P/2006 VW139) was discovered to exhibit comet-like activity by the Pan-STARRS1 survey telescope using automated point-sprea…
Observational and Dynamical Characterization of Main-Belt Comet P/2010 R2 (La Sagra)
Henry H. Hsieh, Bin Yang, Nader Haghighipour +36
We present observations of comet-like main-belt object P/2010 R2 (La Sagra) obtained by Pan-STARRS 1 and the Faulkes Telescope-North on Haleakala in Hawaii, the University of Hawai…
