Polarimetry of Didymos-Dimorphos: Unexpected Long-Term Effects of the DART Impact
Zuri Gray, Stefano Bagnulo, Mikael Granvik +9
We have monitored the Didymos-Dimorphos binary system in imaging polarimetric mode before and after the impact from the Double Asteroid Redirection Test (DART) mission. A previous…
VLT/MUSE Characterisation of Dimorphos Ejecta from the DART Impact
Brian P. Murphy, Cyrielle Opitom, Colin Snodgrass +8
We have observed the Didymos-Dimorphos binary system with the MUSE integral field unit spectrograph mounted at the Very Large Telescope (VLT) pre and post-DART impact, and captured…
Comets CO and CO fluorescence models for measuring the C/C isotopic ratio in CO
Philippe Rousselot, Emmanuel Jehin, Damien Hutsemékers +3
Context: CO is an abundant species in comets, creating CO ion with emission lines that can be observed in the optical spectral range. A good modeling of its fluorescence spectr…
Low NH/HO ratio in comet C/2020 F3 (NEOWISE) at 0.7 au from the Sun
Maria N. Drozdovskaya, Dominique Bockelée-Morvan, Jacques Crovisier +7
A lower-than-solar elemental nitrogen content has been demonstrated for several comets, including 1P/Halley and 67P/C-G with independent in situ measurements of volatile and refrac…
ALMA Observations of the DART Impact: Characterizing the Ejecta at Sub-Millimeter Wavelengths
Nathan X. Roth, Stefanie N. Milam, Anthony J. Remijan +12
We report observations of the Didymos-Dimorphos binary asteroid system using the Atacama Large Millimeter/Submillimeter Array (ALMA) and the Atacama Compact Array (ACA) in support…
Coma environment of comet C/2017 K2 around the water ice sublimation boundary observed with VLT/MUSE
Yuna G. Kwon, Cyrielle Opitom, Manuela Lippi
We report a new imaging spectroscopic observation of Oort-cloud comet C/2017 K2 (hereafter K2) on its way to perihelion at 2.53 au, around a heliocentric distance where H2O ice beg…
