Abstract:
We present a collection of 450598 eclipsing and ellipsoidal binary
systems detected in the OGLE fields toward the Galactic bulge. The
collection consists of binary systems of all types: detached,
semi-detached, and contact eclipsing binaries, RS CVn stars,
cataclysmic variables, HWVir binaries, double periodic variables, and
even planetary transits. For all stars we provide the I- and V-band
time-series photometry obtained during the OGLE-II, OGLE-III, and
OGLE-IV surveys. We discuss methods used to identify binary systems in
the OGLE data and present several objects of particular interest.
Description:
Our collection of binary systems in the Galactic bulge is based on the
photometric data collected by the OGLE survey between 1997 and 2015 at
Las Campanas Observatory, Chile, with the 1.3-m Warsaw Telescope. The
observatory is operated by the Carnegie Institution for Science. In
1997-2000, during the OGLE-II stage, about 30 million stars in the
area of 11 square degrees in the central parts of the Milky Way were
constantly monitored. In 2001, with the beginning of the OGLE-III
survey, the sky coverage was extended to nearly 69 square degrees and
the number of monitored stars increased to 200 million. Finally, from
2010 until today the OGLE-IV project regularly observes about 400
million stars in 182 square degrees of the densest regions of the
Galactic bulge. Our search for eclipsing variables was based primarily
on the OGLE-IV data.
