cds-question@unistra.frglobular-star-clustersvariable-starsccd-photometryVI light-curves of variable stars in the globular cluster M13 are presented. They are based on the CCD observations carried out at the Bialkow station of the Wroclaw University Observatory using 60-cm reflecting telescope and the CCD camera. A 6x4 arcmin-squared field of view covering the core of the cluster was observed through V and I_C filters of the Johnson-Kron-Cousins UBV(RI)_C system. About 300 frames in both filters were taken during 23 nights between 2001 February 27 and August 1. The CCD images were analyzed with the DAOPHOT profile-fitting software and Image Subtraction Method. The main result of this study is discovery of five RR Lyrae and one SX Poenicis stars. Moreover we detect non-radial pulsations in RRc star v36. We also comment the variability of all observed suspected variable stars in M13.2003A&A...398..541Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/398/541CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/398/541https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/398/541http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/398/541https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/398/541https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/398/541http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/398/541GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/398/541/coord (Equatorial coordinates of all observed variable and suspected variable stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/398/541/coord?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/398/541/coord?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/398/541/coord?GETtext/xml+votable180.050000true250.443541736.45769440.0055555555555555566/9436https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/398/541?format=asciiOpticaldefaultJ/A+A/398/541/daovperDAOPHOT V-filter photometry for periodic pulsating stars (BL Her and RR Lyr)recnoRecord number assigned by the VizieR team.
