The Optical Gravitational Lensing Experiment. Eclipsing Binary Stars in the Small Magellanic Cloud

A. Udalski, I. Soszynski, M. Szymanski +4

We present the catalog of 1459 eclipsing binary stars detected in the central 2.4 square degree area of the Small Magellanic Cloud during the OGLE-II microlensing search. The sampl…

The Optical Gravitational Lensing Experiment. Photometry of the MACHO-SMC-98-1 Binary Microlensing Event

A. Udalski, M. Kubiak, M. Szymanski +3

We present photometry of the unique binary microlensing event MACHO-SMC-98-1 collected by the OGLE group. Particularly interesting observation was made close to the first caustic c…

The Optical Gravitational Lensing Experiment. The Catalog of Clusters in the Small Magellanic Cloud

G. Pietrzynski, A. Udalski, M. Kubiak +3

We present the catalog of clusters found in the area of ~2.4 square degree in the central regions of the Small Magellanic Cloud. The catalog contains data for 238 clusters, 72 of t…

The Optical Gravitational Lensing Experiment. BVI Maps of Dense Stellar Regions. I. The Small Magellanic Cloud

A. Udalski, M. Szymanski, M. Kubiak +3

We present three color, BVI maps of the Small Magellanic Cloud. The maps contain precise photometric and astrometric data for about 2.2 million stars from the central regions of th…

Optical Gravitational Lensing Experiment. The Distance Scale: Galactic Bulge - LMC - SMC

A. Udalski

We analyze the mean luminosity of three samples of field RRab Lyr stars observed in the course of the OGLE microlensing experiment: 73 stars from the Galactic bulge and 110 and 128…

Optical Gravitational Lensing Experiment. Distance to the Magellanic Clouds with the Red Clump Stars: Are the Magellanic Clouds 15% Closer than Generally Accepted?

A. Udalski, M. Szymanski, M. Kubiak +3

We present a new distance determination to the Large and Small Magellanic Clouds using the newly developed red clump stars method (Paczynski and Stanek 1998). This new, single-step…
