cds-question@unistra.frvariable-starsWe report on photometric I-band observations of 147 bright (8<I<13) periodic variable stars toward the Galactic bulge including 76 new discoveries. We used one of the HATnet telescopes to obtain 151 exposures spanning 88 nights in 2005 of an 8.4{deg}x8.4{deg} field of view (FOV) approximately centered on (l,b)=(1.73,-4.68). We observed the Galactic bulge in 2005 as part of a microlensing feasibility study, and here we discuss the periodic variable stars we found in our data. Among our discoveries we count 52 new eclipsing binaries and 24 other periodic variable stars.2010AcA....60..261Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AcA/60/261CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/gcvs : General Catalogue of Variable Stars (Samus+ 2007-2010)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)II/264 : ASAS Variable Stars, Southern hemisphere (Pojmanski+, 2002-05)J/AcA/48/35 : All Sky Automated Survey variable stars (Pojmamski 1998)J/AcA/50/177 : All Sky Automated Survey Catalog (Pojmanski+, 2000)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AcA/60/261https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AcA/60/261http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AcA/60/261https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AcA/60/261https://vizier.iucaa.in/viz-bin/votable?-source=J/AcA/60/261http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AcA/60/261GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AcA/60/261/periodic (Eclipsing binaries (table1) and periodic variables of ambiguous classification (table2))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AcA/60/261/periodic?https://vizier.iucaa.in/viz-bin/conesearch/J/AcA/60/261/periodic?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AcA/60/261/periodic?GETtext/xml+votable180.050000true274.9025-33.0219720.0055555555555555565/7181 7186 7194-7195 7198 7205 7216 7218 6/28703 28719 28723 28729-28730 28732 28734-28735 28739-28740 28742-28743 28748 28750-28751 28762 28768-28769 28771-28774 28787-28788 28797-28798 28817 28819 28828-28829 28869-28871 28876 28878 28880-28881 28884 28897https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AcA/60/261?format=asciiOpticaldefaultJ/AcA/60/261/periodicEclipsing binaries (table1) and periodic variables of ambiguous classification (table2)recnoRecord number assigned by the VizieR team.
