J/AcA/56/219 OGLE variable stars in NGC 6259 (Ciechanowska+, 2006) ================================================================================ The Optical Gravitational Lensing Experiment. Variable stars in the field of open cluster NGC 6259. Ciechanowska A., Pietrzynski G., Wyrzykowski L., Szewczyk O., Kubiak M., Udalski A., Szymanski M.K. =2006AcA....56..219C (SIMBAD/NED BibCode) ================================================================================ ADC_Keywords: Clusters, open ; Stars, variable ; Magnitudes Keywords: binaries: eclipsing - stars: oscillations - open clusters and associations: individual: NGC 6259 Abstract: We present the results of a search for variable stars in the field of NGC6259. Altogether 85 variable stars have been discovered. 36 of them are eclipsing systems. This group contains 13 EA, 2 EB and 21 EW-type stars. Light curves of two variable stars resemble those of Miras. The remaining 47 variable stars detected in the field of this open cluster are most probably highly obscured red giants (OSARG, irregular). For all detected variable stars we provide their light curves, preliminary classification, discussion on the possible cluster membership, equatorial coordinates, finding charts and periods when possible. Description: The presented data were collected from July 1997 to September 1999 during 44 nights in the course of the OGLE project (Udalski, Kubiak and Szymanski, 1997AcA....47..319U) at the time, when the weather conditions were too poor to observe the very dense OGLE fields. All observations were made with 1.3m Warsaw telescope located at the Las Campanas Observatory, Chile which is operated by the Carnegie Institution of Washington.
