The Berlin Exoplanet Search Telescope II Catalog of Variable Stars. II. Characterization of the CoRoT SRc02 field

TL;DR

This study used the BEST II telescope to identify and characterize 1,846 variable stars in the CoRoT SRc02 field, significantly expanding the known variable star catalog and providing detailed stellar parameters for select binaries.

Contribution

It presents the first ground-based, high-resolution survey of the CoRoT SRc02 field, discovering new variable stars and modeling key eclipsing binary systems.

Findings

Detected 1,846 variable stars, only 30 previously known.

Modeled stellar parameters for nine eclipsing binaries.

Enhanced understanding of variable star populations in the CoRoT field.

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 the 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 1,846 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 curve.
