The evolution of exocomets and their source populations
Alexander J. Mustill, Tim Pearce, Michele Bannister +12
We review the current state of knowledge of the long-term evolution of the small bodies that give rise to comets and exocomets, as well as their reservoirs. The active cometary pha…
JWST detection of a carbon dioxide dominated gas coma surrounding interstellar object 3I/ATLAS
Martin A. Cordiner, Nathaniel X. Roth, Michael S. P. Kelley +10
3I/ATLAS is the third confirmed interstellar object to visit our Solar System, and only the second to display a clear coma. Infrared spectroscopy with the James Webb Space Telescop…
Water Production Rates of the Interstellar Object 3I/ATLAS
Zexi Xing, Shawn Oset, John Noonan +1
We report the detection of water activity in the third confirmed interstellar object, 3I/ATLAS, based on ultraviolet imaging with the \emph{Neil Gehrels Swift Observatory}'s Ultrav…
Airfall on Comet 67P/Churyumov-Gerasimenko
B. J. R. Davidsson, S. Birch, G. A. Blake +11
We here study the transfer process of material from one hemisphere to the other (deposition of airfall material) on an active comet nucleus, specifically 67P/Churyumov-Gerasimenko.…
Extremely low linear polarization of comet C/2018 V1 (Machholz-Fujikawa-Iwamoto)
E. Zubko, E. Chornaya, M. Zheltobryukhov +8
We measured the degree of linear polarization P of comet C/2018 V1 (Machholz-Fujikawa-Iwamoto) with the broadband Johnson V filter in mid-November of 2018. Within a radius of \r{ho…
The carbon monoxide-rich interstellar comet 2I/Borisov
D. Bodewits, J. W. Noonan, P. D. Feldman +7
Interstellar comets offer direct samples of volatiles from distant protoplanetary disks. 2I/Borisov is the first notably active interstellar comet discovered in our solar system[1]…
Migrating Scarps as a Significant Driver for Cometary Surface Evolution
Samuel Birch, Alexander Hayes, Orkan Umurhan +10
Rosetta observations of 67P/Churyumov-Gerasimenko (67P) reveal that most changes occur in the fallback-generated smooth terrains, vast deposits of granular material blanketing the…
Simultaneous Swift X-ray and UV views of comet C/2007 N3 (Lulin)
J. A. Carter, D. Bodewits, A. M. Read +1
We present an analysis of simultaneous X-Ray and UV observations ofcomet C/2007 N3 (Lulin) taken on three days between January 2009 and March 2009 using the Swift observatory. For…
Cometary Charge Exchange Diagnostics in UV and X-ray
D. Bodewits, D. J. Christian, J. A. Carter +6
Since the initial discovery of cometary charge exchange emission, more than 20 comets have been observed with a variety of X-ray and UV observatories. This observational sample off…
Swift UVOT Grism Spectroscopy of Comets: A First Application to C/2007 N3 (Lulin)
D. Bodewits, G. L. Villanueva, M. J. Mumma +3
We observed comet C/2007 N3 (Lulin) twice on UT 28 January 2009, using the UV grism of the Ultraviolet and Optical Telescope (UVOT) on board the Swift Gamma Ray Burst space observa…
