The Cluster AgeS Experiment (CASE). Variable Stars in the Globular Cluster M55
J. Kaluzny, I. B. Thompson, W. Krzeminski +1
We report time-series photometry for 55 variable stars located in the central part of the globular cluster M55. The sample includes 28 newly identified objects of which 13 are ecli…
An Unusual Eclipsing Blue Straggler V8-NGC 6752
J. Kaluzny, M. Rozyczka, I. B. Thompson +1
We report the analysis of a binary blue straggler in NGC 6752 with a short orbital period of 0.315 d and a W UMA-type light curve. We use photometric data spanning 13 years to plac…
Globular Cluster Ages from Main Sequence Fitting and Detached, Eclipsing Binaries: The Case of 47 Tuc
Aaron Dotter, Janusz Kaluzny, Ian Thompson
Age constraints are most often placed on globular clusters by comparing their CMDs with theoretical isochrones. The recent discoveries of detached, eclipsing binaries in such syste…
Photometric survey of stellar clusters in the outer part of M33. II. Analysis of HST/ACS images
K. Zloczewski, J. Kaluzny
We have used deep ACS/WFC images of M33 to check nature of extended objects detected by the ground based survey of Zloczewski et al. (2008). A total of 24 candidates turned out to…
