cds-question@unistra.frvariable-starsphotometryWe have extracted a total of 1968 Mira variables from the Optical Gravitational Lensing Experiment II (OGLE-II) data base in the Galactic bulge region. Among them, 1960 are associated with 2 Micron All-sky Survey (2MASS) sources, and 1541 are further identified with Midcourse Space Exploration (MSX) point sources. Their photometric properties are compared with those of Mira variables in the Large and Small Magellanic Clouds. We have found that mass-losing stars with circumstellar matter are reddened such that the colour dependence of the absorption coefficient is similar to that of interstellar matter. We also discuss the structure of the bulge. The surface number density of the bulge Mira variables is well correlated with the 2.2-m surface brightness obtained by the Cosmic Background Explorer (COBE) satellite. Using this relation, the total number of Mira variables in the bulge is estimated to be about 6x10^5^. The logP-K relation of the Mira variables gives their space distribution which supports the well-known asymmetry of the bar-like bulge.2005MNRAS.364..117Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/364/117CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AcA/52/129 : DIA OGLE2 candidate variable stars catalog (Wozniak+ 2002)http://www.astrouw.edu.pl/~ogle/ : OGLE Home PageII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)V/114 : MSX6C Infrared Point Source Catalog (Egan+ 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/364/117https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/364/117http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/364/117https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/364/117https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/364/117http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/364/117GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/364/117/table2 (Mira variables)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/364/117/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/364/117/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/364/117/table2?GETtext/xml+votable180.050000true270.6227083-30.40402780.0055555555555555565/7179 7182 7205 7216-7217 6/28704 28706-28707 28713 28725 28727 28734-28735 28768 28770 28776 28778-28779 28819 28828 28857 28860 28880 28882-28883 28886-28887 28893 28908 28910-28911 29058-29059 29062 29065 29068 42349 423518.650015785639275e-20 9.710690472292815e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/364/117?format=asciiOpticaldefaultJ/MNRAS/364/117/table2Mira variablesPerPerioddtime.periodfloatrecnoRecord number assigned by the VizieR team.
