cds-question@unistra.frvariable-starsinfrared-photometryastronomical-object-identificationx-ray-sourcesThe Chinese Small Telescope Array (CSTAR) is the first telescope facility built at Dome A, Antarctica. During the 2008 observing season, the installation provided long-baseline and high-cadence photometric observations in the i-band for 18145 targets within 20deg^2^ CSTAR field around the South Celestial Pole for the purpose of monitoring the astronomical observing quality of Dome A and detecting various types of photometric variability. Using sensitive and robust detection methods, we discover 274 potential variables from this data set, 83 of which are new discoveries. We characterize most of them, providing the periods, amplitudes, and classes of variability.2015ApJS..218...20Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/218/20CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/vsx : AAVSO International Variable Star Index VSX (Watson+, 2006-2014)B/gcvs : General Catalogue of Variable Stars (Samus+ 2007-2013)I/317 : The PPMXL Catalog (Roeser+ 2010)J/AJ/146/139 : 2010 photometry of variable stars from Dome A (Wang+, 2013)J/AJ/142/155 : Variable stars photometry from Dome A (Wang+, 2011)J/AJ/141/166 : HATNet variability survey of K and M dwarfs (Hartman+, 2011)J/PASP/122/347 : Chinese Small Telescope ARray (CSTAR) (Zhou+, 2010)J/MNRAS/385/1749 : UNSW catalog of Variable Stars (Christiansen+, 2008)J/MNRAS/381/851 : SuperWASP-North exoplanet candidates (Clarkson+, 2007)J/MNRAS/379/816 : SuperWASP-North extrasolar planet candidates (Street+, 2007)J/A+A/467/785 : SuperWASP/ROSAT periodic variable stars (Norton+, 2007)http://explore.china-vo.org/ : Chinese astronomical data center home pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/218/20https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/218/20http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/218/20https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/218/20https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/218/20http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/218/20GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/218/20/variables (Catalog of variables in the CSTAR field: recovered (table1) and newly discovered (table2))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/218/20/variables?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/218/20/variables?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/218/20/variables?GETtext/xml+votable180.050000true0.1360833-88.33638890.005555555555555556Cone search capability for table J/ApJS/218/20/table3 (Missed variables during our variability search)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/218/20/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/218/20/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/218/20/table3?GETtext/xml+votable180.050000true11.3615833-88.42258330.0055555555555555565/8192 9216 10240 11264 6/32772 32773 32774 32776 32777 32778 36868 36869 36870 36872 36873 36874 40964 40965 40966 40968 40970 45060 45061 45062 45064 45065 450668.650015785639275e-20 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/218/20?format=asciiInfraredX-raydefaultJ/ApJS/218/20/variablesCatalog of variables in the CSTAR field: recovered (table1) and newly discovered (table2)SpTVizieR MK spectral typesrc.spTypecharrecnoRecord number assigned by the VizieR team.
