Faint star counts with HST
Chris Flynn, Andrew Gould, John Bahcall
We describe a program of star counts in the range 19 < I < 26 made with the WFPC cameras aboard the Hubble Space Telescope. Red (V-I > 1.0) stars at these magnitudes are primarily…
Empirical Calibration of Hubble Space Telescope WFPC2 F606W and F814W Photometry
Samir Salim, Andrew Gould
Using the ground-based V and I photometry of a sample of stars from the Groth Strip, we obtain the first empirical calibration of the F606W and F814W Hubble Space Telescope WFPC2 f…
Galactic Structure From Infrared Surveys
Andrew Gould
By combining the 2MASS and DENIS infrared surveys with the USNO-B proper-motion catalog, it will be possible to map the structure of the Galaxy in unprecedented detail. The key par…
The Hipparcos Proper Motions in Support of the Short RR Lyrae Distance Scale
Piotr Popowski, Andrew Gould
In this paper we investigate whether a misestimate of proper motions could have been a source of substantial systematic errors in the statistical parallax determination of the abso…
