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…
Atomic Oxygen in the Comae of Comets
Anita L. Cochran
We report on the detection of atomic oxygen lines in the spectra of 8 comets. These forbidden lines are a result of the photodissociation of the parent oxygen-bearing species direc…
The Spin-Orbit Alignment of the HD17156 Transiting Eccentric Planetary System
William D. Cochran, Seth Redfield, Michael Endl +1
We present high precision radial velocity observations of HD17156 during a transit of its eccentric Jovian planet. In these data, we detect the Rossiter-McLaughlin effect, which is…
Visible and Near-Infrared Spectrophotometry of the Deep Impact Ejecta of Comet 9P/Tempel 1
Klaus W. Hodapp, Greg Aldering, Karen J. Meech +12
We have obtained optical spectrophotometry of the evolution of comet 9P/Tempel 1 after the impact of the Deep Impact probe, using the Supernova Integral Field Spectrograph (SNIFS)…
Observations of Comet 9P/Tempel 1 with the Keck 1 HIRES Instrument During Deep Impact
Anita L. Cochran, William M. Jackson, Karen J. Meech +1
We report high-spectral resolution observations of comet 9P/Tempel 1 before, during and after the impact on 4 July 2005 UT of the Deep Impact spacecraft with the comet. These obser…
The impact and rotational lightcurves of Comet 9P/Tempel 1
Jean Manfroid, Damien Hutsemékers, Emmanuël Jehin +6
UVES and HIRES high-resolution spectra of comet 9P/Tempel 1 are used to investigate the impact and rotational light curves of various species with a view toward building a simple m…
