Abstract:
We present the first part of a new catalog of variable stars
(OIII-CVS) compiled from the data collected in the course of the third
phase of the Optical Gravitational Lensing Experiment (OGLE-III). In
this paper we describe the catalog of 3361 classical Cepheids detected
in the ∼40 square degrees area in the Large Magellanic Cloud. The
sample consists of 1848 fundamental-mode (F), 1228 first-overtone
(1O), 14 second-overtone (2O), 61 double-mode F/1O, 203 double-mode
1O/2O, 2 double-mode 1O/3O, and 5 triple-mode classical Cepheids. This
sample is supplemented by the list of 23 ultra-low amplitude variable
stars which may be Cepheids entering or exiting instability strip
Description:
The catalog data include VI high-quality photometry collected since
2001, and for some stars supplemented by the OGLE-II photometry
obtained between 1997 and 2000. We provide basic parameters of the
stars: coordinates, periods, mean magnitudes, amplitudes and
parameters of the Fourier light curve decompositions. Our sample of
Cepheids is cross-identified with previously published catalogs of
these variables in the LMC. Individual objects of particular interest
are discussed, including single-mode second-overtone Cepheids,
multiperiodic pulsators with unusual period ratios or Cepheids in
eclipsing binary systems.
