Contact Binaries in OGLE-I Database
M. Szymanski, M. Kubiak, A. Udalski
We present a new catalog of 1575 contact binary stars fainter than I=18 mag identified in OGLE-I database in the selected directions toward the Galactic bulge and the Galactic bar.…
The Optical Gravitational Lensing Experiment. Difference Image Analysis of LMC and SMC data. The Catalog
K. Zebrun, I. Soszynski, P. R. Wozniak +6
We present the first edition of a catalog of variable stars found in the Magellanic Clouds using OGLE-II data obtained during four years: 1997-2000. The catalog covers about 7 squa…
The Optical Gravitational Lensing Experiment. Cepheids in the Galaxy IC1613: No Dependence of the Period--Luminosity Relation on Metallicity
A. Udalski, L. Wyrzykowski, G. Pietrzynski +5
We present results of the search for Cepheids in the galaxy IC1613 carried out as a sub-project of the OGLE-II microlensing survey. 138 Cepheids were found in the 14.2x14.2 arcmin…
Difference Image Analysis of the OGLE-II bulge data. II. Microlensing events
P. R. Wozniak, A. Udalski, M. Szymanski +4
We present a sample of microlensing events discovered in the Difference Image Analysis (DIA) of the OGLE-II images collected during 3 observing seasons, 1997--1999. 4424 light curv…
The Optical Gravitational Lensing Experiment. Cepheids in the Magellanic Clouds. VI. Double-Mode Cepheids in the Large Magellanic Cloud
I. Soszynski, A. Udalski, M. Szymanski +4
We present a sample of 76 double-mode Cepheids detected in the 4.5 square degree area in the central part of the LMC. 19 stars from the sample pulsate in the fundamental mode and t…
