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.
