cds-question@unistra.frvariable-starsinfrared-photometryWe report the results of a diffraction-limited, photometric variability study of the central 5"x5" of the Galaxy conducted over the past 10-years using speckle imaging techniques on the W.M. Keck I 10 m telescope. Within our limiting magnitude of m_K_<16mag for images made from a single night of data, we find a minimum of 15K[2.2um]-band variable stars out of 131 monitored stars. The only periodic source in our sample is the previously identified variable IRS 16SW, for which we measure an orbital period of 19.448+/-0.002-days.2007ApJ...659.1241Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/659/1241CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/523/248 : Variable stars in the Galactic center (Ott+, 1999)J/ApJ/643/1011 : Early-type stars in the center of the Galaxy (Paumard+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/659/1241https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/659/1241http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/659/1241https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/659/1241https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/659/1241http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/659/1241GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/659/1241/GCstars (Stars observed, variable and non-variable)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/659/1241/GCstars?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/659/1241/GCstars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/659/1241/GCstars?GETtext/xml+votable180.050000true266.41716778-29.0080750.0055555555555555566/28830https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/659/1241?format=asciiInfrareddefaultJ/ApJ/659/1241/GCstarsStars observed, variable and non-variableNNumber of nightsdmeta.numberintvarInternal variation (for variables only)magsrc.var.amplitudefloatnullablerecnoRecord number assigned by the VizieR team.
