Contribution

It presents the initial catalog of periodic variables in the Galactic bulge, derived from OGLE observations, with data accessible online for the scientific community.

Findings

Catalog includes 213 variable stars brighter than I=18 mag

Types: pulsating, eclipsing, miscellaneous

Data available online for further research

Abstract

This paper is the first part of the Catalog of Periodic Variable Stars in the Galactic bulge. The Catalog is based on observations collected during the OGLE microlensing search. 213 periodic variable stars brighter than I=18 mag: 31 pulsating, 116 eclipsing and 66 miscellaneous type variables from the Baade's Window BWC field are presented. Periodic variable stars from remaining 20 fields will be presented in similar form in the next parts of the Catalog. The Catalog as well as observations of all periodic variable objects are available to astronomical community over the Internet network.
