| Abstract: |
The OH/IR stars are oxygen-rich, cool giants that lose matter
in the Asymptotic Giant Branch (AGB) phase. In the Galactic
Bulge region, they have a visible light variation. From the
time-series photometric databases in the V-band from the MACHO,
OGLE, ASAS and EROS-2 projects, we retrieved the light curve of
29 OH(1612MHz)/IR in the bulge. By the PDM method, the
characteristics of their light variation are analyzed. |
