Properties of large-amplitude variable stars detected with Two Micron All Sky Survey public images.


Abstract (from CDS):

We 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° ≲ 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° 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.
