Abstract:
Time-series photometry of the CoRoT field SRc02 was obtained by the
Berlin Exoplanet Search Telescope II (BEST II) in 2009. The main aim
was to conduct a ground-based follow-up of the CoRoT field in order to
detect variable stars with better spatial resolution than what can be
achieved with the CoRoT Space Telescope. A total of 1846 variable
stars were detected, of which only 30 have been previously known. For
nine eclipsing binaries the stellar parameters were determined by
modeling their light curves.
Description:
The observations were performed with the BEST II telescope located at
the Universitats-sternwarte Bochum near the Observatorio Cerro
Armazones in Chile. The system consists of a Takahashi 25 cm
Baker-Ritchey-Chretien telescope equipped with a 4kx4k Finger Lakes CCD.
The corresponding field of view is 1.7°x1.7°, with an angular
resolution of 1.5"/pixel. In order to maximize the photon yield and to
get more accurate photometry of the fainter stars, no filter was used.
The exposure time was 120 s for all of the images. BEST II observed
the CoRoT target field SRc02 during a total of 32 nights between 2009
May 4 and July 28.
