cds-question@unistra.frvariable-starsphotometryAmong over 200000 Galactic bulge variable stars in the public domain Optical Gravitational Lensing Experiment (OGLE) catalogue, we found over 15000 red giant variables following two well-defined period-amplitude relations. The periods are in the range 10<P<100d, and amplitudes in the range 0.005<A<0.13mag in the I band. The variables cover a broad range of reddening-corrected colours, 1<(V-I)_0_<5, and a fairly narrow range of extinction-corrected apparent magnitudes, 10.5<I_0_<13. A subset of variables (type A) has an rms scatter of only 0.44mag. The average magnitudes for these stars are well correlated with the Galactic longitude, and vary from I_k,0_=11.82 for l=+8{deg} to I_k,0_=12.07 for l=-5{deg}, clearly indicating that they are located in the Galactic bar. Most variables have several oscillation periods.2004MNRAS.349.1059Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/349/1059CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)J/AcA/52/217 : OGLE VI photometry of Galactic Bulge (Udalski+, 2002)J/AcA/52/129 : DIA OGLE2 cand. variable stars catalog (Wozniak+, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/349/1059https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/349/1059http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/349/1059https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/349/1059https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/349/1059http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/349/1059GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/349/1059/field (OGLE-II bulge fields (from <J/other/AcA/51.175>))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/349/1059/field?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/349/1059/field?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/349/1059/field?GETtext/xml+votable180.050000true270.635417-29.9613890.005555555555555556Cone search capability for table J/MNRAS/349/1059/atype (*Table of all relevant parameters for a sample of type A stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/349/1059/atype?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/349/1059/atype?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/349/1059/atype?GETtext/xml+votable180.050000true270.5397917-30.42077780.005555555555555556Cone search capability for table J/MNRAS/349/1059/btype (*Table of all relevant parameters for a sample of type B stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/349/1059/btype?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/349/1059/btype?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/349/1059/btype?GETtext/xml+votable180.050000true270.5272917-30.41736110.0055555555555555565/7179 7182 7205 7216-7217 7220 6/28704 28706-28707 28713 28725 28727 28734-28735 28768 28770 28778-28779 28782 28819 28828 28857 28860 28886-28887 28893 28908 28910-28911 29058-29059 29062 29065 29068 42349 423518.650015785639275e-20 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/349/1059?format=asciiOpticaldefaultJ/MNRAS/349/1059/fieldOGLE-II bulge fields (from <J/other/AcA/51.175>)recnoRecord number assigned by the VizieR team.
