Absolute Magnitudes and Colors of RR Lyrae stars in DECam Passbands from Photometry of the Globular Cluster M5
A. Katherina Vivas, Abhijit Saha, Knut Olsen +10
We characterize the absolute magnitudes and colors of RR Lyrae stars in the globular cluster M5 in the ugriz filter system of the Dark Energy Camera (DECam). We provide empirical P…
Towards a Network of Faint DA White Dwarfs as High-Precision Spectrophotometric Standards
Gautham Narayan, Tim Axelrod, Jay B. Holberg +8
We present initial results from a program aimed at establishing a network of hot DA white dwarfs to serve as spectrophotometric standards for present and future wide-field surveys.…
Long-term photometric monitoring of RR Lyr stars in M3
J. Jurcsik, G. Hajdu, B. Szeidl +6
The period-change behaviour of 134 RR Lyrae stars in the globular cluster Messier 3 (M3) is investigated on the ~120-year time base of the photometric observations. The mean period…
Calibration of BVRI Photometry for the Wide Field Channel of the HST Advanced Camera for Surveys
Abhijit Saha, Richard A. Shaw, Jennifer A. Claver +1
We present new observations of two Galactic globular clusters, PAL4 and PAL14, using the Wide-Field Channel of the Advanced Camera for Surveys (ACS) on board the Hubble Space Teles…
First Results from the NOAO Survey of the Outer Limits of the Magellanic Clouds
Abhijit Saha, Edward W. Olszewski, Brian Brondel +11
[abridged] We describe the first results from the NOAO Outer Limits Survey. The survey consists of deep images of 55 0.6x0.6 degree fields at distances up to 20 degrees from the LM…
Variable Stars in Leo A: RR Lyraes, Short-period Cepheids, and Implications on Stellar Content
A. E. Dolphin, A. Saha, J. Claver +6
We present the results of a search for short-period variable stars in Leo A. We have found 92 candidate variables, including eight candidate RR Lyrae stars. From the RR Lyraes, we…
