Photometric Survey for Stellar Clusters in the Outer Part of M33
K. Zloczewski, J. Kaluzny, J. Hartman
We present a catalog of 4780 extended sources from the outer field of M33. The catalog includes 73 previously identified clusters or planetary nebulae, 1153 likely background galax…
Variability Study of EHB Stars in the Globular Cluster NGC 6752
J. Kaluzny, I. B. Thompson
We present the results of a search for variable stars in the central part of the globular cluster NGC 6752. The monitored sample included 160 BHB and 107 EHB stars, respectively. A…
The Clusters AgeS Experiment (CASE). II. The Eclipsing Blue Straggler OGLEGC-228 in the Globular Cluster 47 Tuc
J. Kaluzny, I. B. Thompson, S. M. Rucinski +4
We use photometric and spectroscopic observations of the eclipsing binary OGLEGC-228 (V228) to derive the masses, radii, and luminosities of the component stars. Based on measured…
The Clusters AgeS Experiment (CASE). I. V209 omega Cen - An Eclipsing Post-Common Envelope Binary in the Globular Cluster omega Cen
J. Kaluzny, S. M. Rucinski, I. B. Thompson +2
We use photometric and spectroscopic observations of the detached eclipsing binary V209 omega Cen to derive the masses, radii, and luminosities of the component stars. The system e…
Cluster AgeS Experiment (CASE): Dwarf Novae and a Probable Microlensing Event in the Globular Cluster M22
P. Pietrukowicz, J. Kaluzny, I. B. Thompson +4
We report the identification of a new cataclysmic variable (denoted as CV2) and a probable microlensing event in the field of the globular cluster M22. Two outbursts were observed…
Variable Stars in the Archival HST Data of Globular Clusters M13, M30 and NGC 6712
Pawel Pietrukowicz, Janusz Kaluzny
We have analyzed archival HST/WFPC2 time-series data of the central parts of globular clusters M13, M30 and NGC 6712 in search of variable objects. Among a total of 21 identified v…
