Kinematics of Stars in Kapteyn Selected Area 71: Sampling the Monoceros and Sagittarius Tidal Streams
Dana I. Casetti-Dinescu, Jeffrey L. Carlin, Terrence M. Girard +3
We present a 3D kinematical analysis of stars located in Kapteyn Selected Area 71 (l = 167.1, b = -34.7), where previously a stellar excess was found (Dinescu et al. 2002, Newberg…
The vertical velocity dispersion profile of the Galactic thick disk
C. Moni Bidin, T. M. Girard, G. Carraro +4
We present the results of radial velocity measurements of 770 thick disk red giants toward the South Galactic Pole, vertically distributed from 0.5 kpc to 5 kpc with respect to the…
Proper Motions in the Galactic Bulge: Plaut's Window
Katherine Vieira, Dana I. Casetti-Dinescu, Rene A. Mendez +6
A proper motion study of a field of 20' x 20' inside Plaut's low extinction window (l,b)=(0 deg,-8 deg), has been completed. Relative proper motions and photographic BV photometry…
Space Velocities of Southern Globular Clusters. V. A Low Galactic Latitude Sample
D. I. Casetti-Dinescu, T. M. Girard, D. Herrera +3
We have measured the absolute proper motions of globular clusters NGC 2808, 3201, 4372, 4833, 5927 and 5986. The proper motions are on the Hipparcos system and they are the first d…
A Deep Proper-Motion Survey in Kapteyn Selected Areas: I. Survey Description and First Results for Stars in the Tidal Tail of Sagittarius and in the Monoceros Ring
Dana I. Casetti-Dinescu, Steven R. Majewski, Terrence M. Girard +4
We describe a high-precision, deep (to V ~ 19-21) absolute proper-motion survey that samples ~50 lines of sight in the Kapteyn Selected Areas along declination zones -15, 0 and 15…
Velocity Shear of the Thick Disk from SPM3 Proper Motions at the South Galactic Pole
T. M. Girard, V. I. Korchagin, D. I. Casetti-Dinescu +3
The kinematical properties of the Galactic Thick Disk are studied using absolute proper motions from the SPM3 Catalog and 2MASS near-infrared photometry for a sample of ~1200 red g…
