Comet C/2004 Q2 (Machholz): parent volatiles, a search for deuterated methane, and constraint on the CH_4 spin temperature (2009)

Bonev, Boncho P., Mumma, Michael J., Gibb, Erika L., DiSanti, Michael A., Villanueva, Geronimo L., Magee-Sauer, Karen, ...

High-dispersion (λ/δλ ≈ 25,000) infrared spectra of Comet C/2004 Q2 (Machholz) were acquired on 2004 November 28-29, and 2005 January 19 (UT dates) with the Near InfraRed echelle SPECtrograph...

Bonev, Boncho P., Mumma, Michael J., Gibb, Erika L., Disanti, Michael A., Villanueva, Geronimo L., Magee-Sauer, Karen, ...

High-dispersion (l/dl ~ 25,000) infrared spectra of Comet C/2004 Q2 (Machholz) were acquired on Nov. 28-29, 2004, and Jan. 19, 2005 (UT dates) with NIRSPEC at the Keck-2 telescope on Mauna Kea. We...

A Search for Variation in the H_2O Ortho-Para Ratio and Rotational Temperature in the Inner Coma of Comet C/2004 Q2 (Machholz) (2007)

Bonev, Boncho P., Mumma, Michael J., Villanueva , Geronimo L., Disanti, Michael A., Ellis, Richard S., Magee-Sauer, Karen, ...

We present spatially resolved measurements of the rotational temperature and ortho-para ratio for H_2O in the inner coma of the Oort Cloud comet C/2004 Q2 (Machholz). Our results are based on direct...
