The Excited Spin State of Dimorphos Resulting from the DART Impact
Harrison F. Agrusa, Ioannis Gkolias, Kleomenis Tsiganis +12
The NASA Double Asteroid Redirection Test (DART) mission is a planetary defense-driven test of a kinetic impactor on Dimorphos, the satellite of the binary asteroid 65803 Didymos.…
Knowledge Gaps in the Cometary Spectra of Oxygen-Bearing Molecular Cations
Ryan Fortenberry, Dennis Bodewits, Donna Pierce
Molecular cations are present in various astronomical environments, most notably in cometary atmospheres and tails where sunlight produces exceptionally bright near-UV to visible t…
Six Outbursts of Comet 46P/Wirtanen
Michael S. P. Kelley, Tony L. Farnham, Jian-Yang Li +32
Cometary activity is a manifestation of sublimation-driven processes at the surface of nuclei. However, cometary outbursts may arise from other processes that are not necessarily d…
Time-series and Phasecurve Photometry of Episodically-Active Asteroid (6478) Gault in a Quiescent State Using APO, GROWTH, P200 and ZTF
Josiah N. Purdum, Zhong-Yi Lin, Bryce T. Bolin +49
We observed Episodically Active Asteroid (6478) Gault in 2020 with multiple telescopes in Asia and North America and have found that it is no longer active after its recent outburs…
Ice-Coated Pebble Drift as a Possible Explanation for Peculiar Cometary CO/H2O Ratios
Ellen M. Price, L. Ilsedore Cleeves, Dennis Bodewits +1
To date, at least three comets -- 2I/Borisov, C/2016 R2 (PanSTARRS), and C/2009 P1 (Garradd) -- have been observed to have unusually high CO concentrations compared to water. We at…
Activity of the first interstellar comet 2I/Borisov around perihelion: Results from Indian observatories
Aravind Krishnakumar, Shashikiran Ganesh, Kumar Venkataramani +4
Comet 2I/Borisov is the first true interstellar comet discovered. Here we present results from observational programs at two Indian observatories, 2 m Himalayan Chandra Telescope a…
