cds-question@unistra.freclipsing-binary-starsvariable-starsccd-photometryThe Berlin Exoplanet Search Telescope II (BEST II) is a small wide field-of-view photometric survey telescope system located at the Observatorio Cerro Armazones, Chile. The high duty cycle combined with excellent observing conditions and millimagnitude photometric precision makes this instrument suitable for ground based support observations for the CoRoT space mission. Photometric data of the CoRoT LRa02 target field collected between November 2008 and March 2009 were analysed for stellar variability. The presented results will help in the future analysis of the CoRoT data, particularly in additional science programs related to variable stars. BEST II observes selected CoRoT target fields ahead of the space mission. The photometric data acquired are searched for stellar variability, periodic variable stars are identified with time series analysis of the obtained stellar light curves. We obtained the light curves of 104335 stars in the CoRoT LRa02 field over 41 nights. Variability was detected in light curves of 3726 stars of which 350 showed a regular period. These stars are, with the exception of 5 previously known variable stars, new discoveries.2009A&A...506..569Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/506/569CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/corot : CoRoT observation log (CoRoT, 2009)B/vsx : AAVSO International Variable Star Index VSX (Watson+, 2009)B/gcvs : General Catalogue of Variable Stars (Samus+ 2007-2009)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)I/252 : The USNO-A2.0 Catalogue (Monet+ 1998)J/AJ/134/766 : BEST variable stars in LRc1 field (Karoff+, 2007)J/AJ/134/1560 : BEST periodic variable stars in IR01 field (Kabath+, 2007)J/AJ/136/654 : BEST periodic variable stars in LRa1 field (Kabath+, 2008)J/AJ/137/3911 : BEST periodic variable stars in LRc2 field (Kabath+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/506/569https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/506/569http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/506/569https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/506/569https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/506/569http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/506/569GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/506/569/variables (Combined table from original tables)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/506/569/variables?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/506/569/variables?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/506/569/variables?GETtext/xml+votable180.050000true101.8575-3.9056670.0055555555555555565/5510 6/22023 22029 22034-22035 22044 22046 22065 22068https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/506/569?format=asciidefaultJ/A+A/506/569/variablesCombined table from original tablesrecnoRecord number assigned by the VizieR team.
