cds-question@unistra.freclipsing-binary-starsphotometryA photometric survey of three southern target fields with BEST II yielded the detection of 2406 previously unknown variable stars and an additional 617 stars with suspected variability. This study presents a catalog including their coordinates, magnitudes, light curves, ephemerides, amplitudes, and type of variability. In addition, the variability of 17 known objects is confirmed, thus validating the results. The catalog contains a number of known and new variables that are of interest for further astrophysical investigations, in order to, e.g., search for additional bodies in eclipsing binary systems, or to test stellar interior models. Altogether, 209070 stars were monitored with BEST II during a total of 128 nights in 2009/2010. The overall variability fraction of 1.2%-1.5% in these target fields is well comparable to similar ground-based photometric surveys. Within the main magnitude range of R{isin}[11, 17], we identify 0.67(3)% of all stars to be eclipsing binaries, which indicates a completeness of about one third for this particular type in comparison to space surveys.2013AJ....146..136Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/146/136CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/gcvs : General Catalogue of Variable Stars (Samus+ 2007-2013)I/322 : UCAC4 Catalogue (Zacharias+, 2012)II/264 : ASAS Variable Stars in Southern hemisphere (Pojmanski+, 2002-2005)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)J/AJ/143/140 : BEST-II periodic variables in CoRoT LRa02.
