Photometry and Spectroscopy of GRB 030329 and Its Associated Supernova 2003dh: The First Two Months
T. Matheson, P. M. Garnavich, K. Z. Stanek +4
We present extensive optical and infrared photometry of the afterglow of gamma-ray burst (GRB) 030329 and its associated supernova (SN) 2003dh over the first two months after detec…
Cluster AgeS Experiment (CASE): RR Lyrae stars from the globular cluster Omega Centauri as standard candles
A. Olech, J. Kaluzny, I. B. Thompson +1
New photometry of RRab and RRc stars in Omega Cen is used to calibrate their absolute magnitudes M_V as a function of: a) metallicity; and b) the Fourier parameters of light curves…
DIRECT Distances to Nearby Galaxies Using Detached Eclipsing Binaries and Cepheids. IX. Variables in the Field M31Y Discovered with Image Subtraction
A. Z. Bonanos, K. Z. Stanek, D. D. Sasselov +3
The DIRECT Project aims to obtain direct distances to two Local Group galaxies, M31 and M33, which occupy a crucial position near the bottom of the cosmological distance ladder. Th…
Variable Yellow and Red Stragglers in the Old Open Cluster NGC 6791
Janusz Kaluzny
Two sets of archive time series observations of an old open cluster NGC 6791 were re-analysed using an image subtraction technique. We report identification of four new variables.…
Long-term variability survey of the old open cluster NGC 6791
B. J. Mochejska, K. Z. Stanek, J. Kaluzny
We present the results of a long-term variability survey of the old open cluster NGC 6791. The BVI observations, collected over a time span of 6 years, were analyzed using the ISIS…
