OGLE2 Mira variables in the Galactic bulge
Listed in IVOA Registry (Virtual Observatory)
We have extracted a total of 1968 Mira variables from the Optical Gravitational Lensing Experiment II (OGLE-II) data base in the Galactic bulge region.
Description
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.
