J/PASJ/54/719    IRAS/SiO sources in the Galactic bulge   (Deguchi+, 2002)

Near-infrared observations of the IRAS/SiO sources in the Galactic bulge: a large scale distribution. Deguchi S., Fujii T., Nakashima J., Wood P.R. <Publ. Astron. Soc. Jap., 54, 719 (2002)> =2002PASJ...54..719D
ADC_Keywords: Infrared sources ; Photometry, infrared ; Masers Keywords: galaxies: Milky Way - infrared: sources - stars: kinematics - stars: long-period variables - stars: mass-loss Description: Near-infrared imaging observations of IRAS sources with SiO masers were made with the 2.3-m telescope of the Australian National University at Siding Spring Observatory, Australia, on 1997 June 18-23, 1998 June 9-12, and 2000 July 16-19, using the infrared array camera CASPIR. These infrared observations were made in parallel with long-term (1997-1999) SiO maser surveys at Nobeyama. The near-infrared observations were made within a year or so of the SiO detections. The details of the observations, data reduction, and method of identification were described in Deguchi et al. (1998PASJ...50..597D, 2001, Cat. J/PASJ/53/293), so they are not repeated here. All of the sources discussed in this paper are IRAS sources with detected SiO masers in the sky region of -10°<l<15° and |b|<3° (Deguchi et al., 2000ApJS..130..351D). File Summary:
