The Optical Gravitational Lensing Experiment. Eclipsing Binary Stars in the Large Magellanic Cloud
L. Wyrzykowski, A. Udalski, M. Kubiak +6
We present the catalog of 2580 eclipsing binary stars detected in 4.6 square degree area of the central parts of the Large Magellanic Cloud. The photometric data were collected dur…
The Optical Gravitational Lensing Experiment. BVI Maps of Dense Stellar Regions. III. The Galactic Bulge
A. Udalski, M. Szymanski, M. Kubiak +6
We present the VI photometric maps of the Galactic bulge. They contain VI photometry and astrometry of about 30 million stars from 49 fields of 0.225 square degree each in the Gala…
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…
The Optical Gravitational Lensing Experiment. A Hunt for Caustic Crossings in QSO 2237+0305
P. R. Wozniak, A. Udalski, M. Szymanski +5
In 1998 The Optical Gravitational Lensing Experiment (OGLE) successfully implemented automated data reductions for QSO 2237+0305. Using a new image subtraction method we achieved a…
The Optical Gravitational Lensing Experiment. Catalog of Microlensing Events in the Galactic Bulge
A. Udalski, K. Zebrun, M. Szymanski +4
We present the Catalog of microlensing events detected toward the Galactic bulge in three observing seasons, 1997--1999, during the OGLE-II microlensing survey. The search for micr…
The Optical Gravitational Lensing Experiment. Cepheids in the Magellanic Clouds. III. Period-Luminosity-Color and Period-Luminosity Relations of Classical Cepheids
A. Udalski, M. Szymanski, M. Kubiak +4
We present Period-Luminosity-Color and Period-Luminosity relations of classical Cepheids constructed for about 1280 Cepheids from the LMC and 2140 from the SMC. High quality BVI ob…
