Isotopic composition of cometary water and the origin of Earth's oceans
Dariusz C. Lis, Martin Cordiner, Nicolas Biver +4
Studies of the water content and isotopic composition of water-rich asteroids and comets are of key interest for understanding the late accretion stage of the Solar System cometary…
Gas Sources from the Coma and Nucleus of Comet 46P/Wirtanen Observed Using ALMA
M. A. Cordiner, N. X. Roth, S. N. Milam +10
Gas-phase molecules in cometary atmospheres (comae) originate primarily from (1) outgassing by the nucleus, (2) sublimation of icy grains in the near-nucleus coma, and (3) coma (ph…
Water Ortho-to-Para ratio in the coma of comet 67P/Churyumov-Gerasimenko
Y. -C. Cheng, D. Bockelée-Morvan, M. Roos-Serote +9
Abundance ratios of the nuclear-spin isomers of HO and NH have been measured in about two dozen comets, with a mean value corresponding to a nuclear-spin temperature of $\s…
Spatial Distribution of Ultraviolet Emission from Cometary Activity at 67P/Churyumov-Gerasimenko
John W. Noonan, Dominique Bockelée-Morvan, Paul D. Feldman +16
The Alice ultraviolet spectrograph on board the \textit{Rosetta} orbiter provided the first near-nucleus ultraviolet observations of a cometary coma from arrival at comet 67P/Chury…
Analysis of Hybrid Gas-Dust Outbursts Observed at 67P/Churyumov-Gerasimenko
John W. Noonan, Giovanna Rinaldi, Paul D. Feldman +14
Cometary outbursts offer a valuable window into the composition of comet nuclei with their forceful ejection of dust and volatiles in explosive events, revealing the interior compo…
Characterization of Thermal Infrared Dust Emission and Refinements to the Nucleus Properties of Centaur 29P/Schwassmann-Wachmann 1
Charles A. Schambeau, Yanga R. Fernandez, Nalin H. Samarasinha +4
We present analyses of Spitzer observations of 29P/Schwassmann-Wachmann 1 using 16 m IRS "blue" peak-up (PU) and 24 m and 70 m MIPS images obtained on UT 2003 November 23…
