ADC_Keywords: Binaries, eclipsing ; Stars, variable ; Photometry, UBVRI Keywords: catalogs; binaries: eclipsing; stars: variables: delta Scuti; stars: variables: general; stars: variables: RR Lyrae; techniques: photometric Abstract: We used the large photometric database of the ASTEP program, whose primary goal was to detect exoplanets in the southern hemisphere from Antarctica, to search for eclipsing binaries (EcBs) and variable stars. 673 EcBs and 1166 variable stars were detected, including 31 previously known stars. The resulting online catalogs give the identification, the classification, the period, and the depth or semi-amplitude of each star. Data and light curves for each object are available at http://astep-vo.oca.eu/. Description: Observations were carried out using the ASTEP 400 telescope; located at Dome C (75°06'S, 123°21'E) in Antarctica at an altitude of 3233m. Scientific ASTEP 400 observations were conducted from 2010 to 2012, between the beginning of March through the end of September of each polar campaign. Table 1 lists the coordinates, the exposure time, the observation period, the number of frames, and the available observation time of each observed stellar field. More than 150000 images were collected for a total integration time of 3729hr. File Summary:

Note (1): Variable type as follows: LPV = Long Period Variable (609 sources) Variable = Not classified variable (253 sources) Rot. V = Rotational variable (93 sources) RR Lyrae = RR Lyrae (85 sources) δ Scuti = δ Scuti star (70 sources) γ Doradus = γ Doradus star (34 sources) Hybrid = Hybrid γ Doradus-δ Scuti star (22 sources). Hybrid stars are listed twice with the same values for the first 12 columns. The period, amplitude and comments are different. Cepheid = Cepheid variable (1 source) Note (2): The γ Doradus stars with asymmetric light curves (large variations in the maximum brightness and much smaller variations in the minimum brightness) are noted "Asym.".
Global notes: Note (G1): Magnitudes from UCAC4 (I/322).
