The OGLE Collection of Variable Stars. One Thousand Heartbeat Stars in the Galactic Bulge and Magellanic Clouds

Abstract

We present a collection of 991 heartbeat star (HBS) candidates found in the Optical Gravitational Lensing Experiment (OGLE) project data archive. We discuss the selection process of the HBS candidates and the structure of the catalog itself. It consists of 512 stars located toward the Galactic bulge (GB), 439 stars located in the Large Magellanic Cloud (LMC), and 40 in the Small Magellanic Cloud (SMC). The collection contains two large groups of HBSs with different physical properties. The main distinction between the two groups is the evolutionary status of the primary star. The first group of about 100 systems contains a hot main-sequence (MS) or a Hertzsprung-gap primary star, while the second group of about 900 systems includes a red giant (RG). For each star, we provide two-decade-long time-series photometry, in the Cousins $I$- and Johnson $V$-band filters, obtained by the OGLE project. We also present basic observational information as well as orbital parameters derived from the light curve modeling.

13 pages (17 pages in arXiv version), 11 figures, 5 tables. The full machine-readable tables are provided by the publisher. The catalog is available via OGLE website: https://astrouw.edu.pl/ogle/ogle4/OCVS/. Erratum; in the publisher version of the paper, there are wrong reference numbers to the figures from Paper II: Figures 8--9 --> Figures 9--10, Figure 10 --> Figure 11, Figure 11 --> Figure 12
