Abstract:
We present a large sample of eclipsing binary stars detected in the
Small Magellanic Cloud fields covering about 14 square degrees that
have been monitored for eight years during the third phase of the
OGLE survey. This is the largest set of such variables containing
6138 objects, of which 777 are contact and 5361 non-contact binaries.
The estimated completeness of this sample is around 82%. We analyze
the statistical properties of the sample and present selected
interesting objects: 32 systems having eccentric orbit with visible
apsidal motion, one Transient Eclipsing Binary, ten RS CVn type
stars, 22 still unexplained Double-Periodic Variable stars, and 15
candidates for doubly eclipsing quadruple systems. Based on the
OGLE-III proper motions, we classified 47 binaries from our sample as
foreground Galactic stars. We also list candidates suitable for the
SMC distance determination.
Description:
All the data presented in this paper were collected with the 1.3-m
Warsaw telescope at the Las Campanas Observatory in Chile. The
observatory is operated by the Carnegie Institution for Science.
During the OGLE-III phase, the telescope was equipped with a mosaic
eight-chip camera, with the field of view of about 35'x35' and the
scale of 0.26"/pixel.
