J/A+A/473/143  Radial velocities of C stars near Galactic plane  (Demers+, 2007)

C stars as kinematic probes of the Milky Way disk from 9 to 15 kpc. Demers S., Battinelli P. <Astron. Astrophys., 473, 143-148 (2007)> =2007A&A...473..143D
ADC_Keywords: Galactic plane ; Stars, carbon ; Photometry, infrared ; Radial velocities Keywords: stars: carbon - stars: kinematics - Galaxy: disk - Galaxy: kinematics and dynamics Abstract: The availability, from 2MASS, of a large homogeneous sample of Galactic C stars and the recognition that their absolute magnitude can be accurately determined offer the possibility to use them as kinematical probes to investigate motions in the thin or thick disks. Our aims is to determine the radial velocities for 70 C stars, a few degrees from the Galactic plane and distributed in longitudes from 60° to 220°. Description: Spectra were obtained during six nights in October 2006 with the spectrograph attached to the Cassegrain focus of the Dominion Astrophysical Observatory 1.8m Plaskett Telescope.
