VizieR Online Data Catalog: Heartbeat stars in the Gal. bulge & MCs from OGLE (Wrona+, 2022)

In this work, we use data collected mainly during the fourth phase of the OGLE project (OGLE-IV), which lasted from 2010 March until 2020 March, when the COVID-19 pandemic forced the OGLE operations to stop. All the observations were taken using the 1.3m Warsaw telescope, which is located at Las Campanas Observatory, Chile (the facility site is operated by the Carnegie Institution for Science). The vast majority of photometric data were collected in a Cousins I-band filter.

In the catalog, we also provide data from earlier phases of the OGLE project--OGLE-II and OGLE-III, which took place from 1997 to 2000 and from 2001 to 2009, respectively. About 90% of our sample of heartbeat stars (HBSs) were observed during the OGLE-III (the mean number of epochs is about 720) and 30% during the OGLE-II (350 epochs on average).
