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…
First Detection of Molecular Activity in the Largest Known Oort Cloud Comet: ALMA Imaging of C/2014 UN271 (Bernardinelli-Bernstein) at 16.6 au from the Sun
Nathan X. Roth, Stefanie N. Milam, Martin A. Cordiner +12
We report observations of comet C/2014 UN271 (Bernardinelli-Bernstein) carried out on UT 2024 March 8 and 17 at a heliocentric distance () of 16.6 au using the Atac…
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…
Photometry of the Didymos system across the DART impact apparition
Nicholas Moskovitz, Cristina Thomas, Petr Pravec +78
On 26 September 2022, the Double Asteroid Redirection Test (DART) spacecraft impacted Dimorphos, the satellite of binary near-Earth asteroid (65803) Didymos. This demonstrated the…
Ejecta Evolution Following a Planned Impact into an Asteroid: The First Five Weeks
Theodore Kareta, Cristina Thomas, Jian-Yang Li +85
The impact of the DART spacecraft into Dimorphos, moon of the asteroid Didymos, changed Dimorphos' orbit substantially, largely from the ejection of material. We present results fr…
Orbital Period Change of Dimorphos Due to the DART Kinetic Impact
Cristina A. Thomas, Shantanu P. Naidu, Peter Scheirich +46
The Double Asteroid Redirection Test (DART) spacecraft successfully performed the first test of a kinetic impactor for asteroid deflection by impacting Dimorphos, the secondary of…
Photometry and model of near-Earth asteroid 2021 DW1 from one apparition
T. Kwiatkowski, P. Koleńczuk, A. Kryszczyńska +17
On 4 March 2021 at 9 UTC a 30-m in diameter near-Earth asteroid 2021 DW1 passed the Earth at a distance of 570000 km, reaching the maximum brightness of V=14.6 mag. We observed it…
