cds-question@unistra.frvariable-starsinfrared-sourcesinfrared-photometryWe present a catalog of variable stars in the near-infrared wavelength detected with overlapping regions of the Two Micron All Sky Survey public images, and discuss their properties. The investigated region is in the direction of the Galactic center (-30{deg}<~l<~20, |b|<~20), which covers the entire bulge. We have detected 136 variable stars, of which six are already known and 118 are distributed in the |b|<5{deg} region. Additionally, 84 variable stars have optical counterparts in Digitized Sky Survey images. The three diagrams (color-magnitude, light variance, and color-color diagrams) indicate that most of the detected variable stars should be large-amplitude and long-period variables such as Mira variables or OH/IR stars. The number density distribution of the detected variable stars implies that they trace the bar structure of the Galactic bulge.2009AJ....138.1508Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/138/1508CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/138/1508https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/138/1508http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/138/1508https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/138/1508https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/138/1508http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/138/1508GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/138/1508/table1 (List of 2MASS variables)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/138/1508/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/138/1508/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/138/1508/table1?GETtext/xml+votable180.050000true265.32125-25.2097220.0055555555555555566/28686 28705 28706 28707 28715 28758 28779 28780 28782 28784 28787 28794 28801 28804 28806 28807 28813 28826 28849 28852 28853 28855 28865 28868 28870 28871 28879 28881 28884 28886 28887 28888 28889 28893 28895 28898 28903 28904 28905 28909 28910 28911 28913 28916 28917 28919 28920 28922 28925 29001 29055 29059 29089 29091 29096 29097 29100 29106 29107 29108 29110 29117 29119 29163 29186 29213 29235 29253 29258 29264 29265 29443 29448 29452 29507 29511 42349 42353 42354 42362 42365 42372 42376 42377 42380 42384 42385 42461 42586 42956 478718.650015785639275e-20 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/138/1508?format=asciiInfrareddefaultJ/AJ/138/1508/table1List of 2MASS variablesrecnoRecord number assigned by the VizieR team.
