Thirty Years of Cometary Spectroscopy from McDonald Observatory
Anita L. Cochran, Edwin S. Barker, Candace L. Gray
We report on the results of a spectroscopic survey of 130 comets that was conducted at McDonald observatory from 1980 through 2008. Some of the comets were observed on only one nig…
Placing the Deep Impact Mission into Context: Two Decades of Observations of 9P/Tempel 1 from McDonald Observatory
Anita L. Cochran, Edwin S. Barker, Marcos D. Caballero +1
We report on low-spectral resolution observations of comet 9P/Tempel 1 from 1983, 1989, 1994 and 2005 using the 2.7m Harlan J. Smith telescope of McDonald Observatory. This comet w…
N and CO in Comets 122P/1995 S1 (deVico) and C/1995 O1 (Hale-Bopp)
Anita L. Cochran, William D. Cochran, Edwin S. Barker
We observed comets 122P/1995\,S1 (deVico) and C/1995\,O1 (Hale-Bopp) with high spectral resolving power in order to determine the ratio of N/CO in their comae. While we c…
