Splitting of Long-Period Comet C/2018 F4 (PANSTARRS)
Man-To Hui, Michael S. P. Kelley, Denise Hung +4
Long-period comet C/2018 F4 (PANSTARRS) was observed to show duplicity of its inner region in 2020 September, suggestive of a splitting event. We here present analyses of our obser…
Comet P/2021 HS (PANSTARRS) and the Challenge of Detecting Low-Activity Comets
Quanzhi Ye, Michael S. P. Kelley, James M. Bauer +8
Jupiter-family comet (JFC) P/2021 HS (PANSTARRS) only exhibits a coma within a few weeks of its perihelion passage at 0.8~au, which is atypical for a comet. Here we present an inve…
Observational Characterization of Main-Belt Comet and Candidate Main-Belt Comet Nuclei
Henry H. Hsieh, Marco Micheli, Michael S. P. Kelley +9
We report observations of nine MBCs or candidate MBCs, most of which were obtained when the targets were apparently inactive. We find effective nucleus radii (assuming albedos of p…
Determining the dust environment of an unknown comet for a spacecraft fly-by: The case of ESA's Comet Interceptor mission
Raphael Marschall, Vladimir Zakharov, Cecilia Tubiana +12
We present a statistical approach to assess the dust environment for a yet unknown comet (or when its parameters are known only with large uncertainty). This is of particular impor…
Continued PSP/WISPR Observations of a Phaethon-related Dust Trail
Karl Battams, Angel J. Gutarra-Leon, Brendan M. Gallagher +7
We present an update to the first white-light detections of a dust trail observed closely following the orbit of asteroid (3200) Phaethon, as seen by the Wide-field Imager for Park…
A LOOK at Outbursts of Comet C/2014 UN (Bernardinelli-Bernstein) Near 20 au
Michael S. P. Kelley, Rosita Kokotanekova, Carrie E. Holt +10
Cometary activity may be driven by ices with very low sublimation temperatures, such as carbon monoxide ice, which can sublimate at distances well beyond 20 au. This point is empha…
