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…
SMC: Stellar Populations through deep CMDs
Noelia E. D. Noel, Carme Gallart, Edgardo Costa +1
We present deep color-magnitud diagrams (CMDs) reaching the oldest main-sequence turnoffs for 12 fields in the SMC. The {\it B}-band and {\it R}-band observations were performed us…
The interplay of observational errors through numerical simulations using the method for magnitude and proper-motion samples of local disk white dwarfs.}
Rene A. Mendez, Maria T. Ruiz
White dwarf cooling sequences provides a useful indicator of the evolutionary time scales involved in the chronometry and star formation history of the galactic disk and, for this…
A Large Proper-Motion Survey in Plaut's Low-Extinction Window
R. A. Mendez, R. M. Rich, W. F van Altena +3
We present preliminary results from the deepest and largest photographic proper-motion survey ever undertaken of the Galactic bulge. Our first-epoch plate material (from 1972-3) go…
