JVN observations of H2O masers around the evolved star IRAS 22480+6002
H. Imai, T. Fujii, T. Omodaka +1
We report on the H2O maser distributions around IRAS 22480+6002 (=IRC+60370) observed with the Japanese VLBI Network (JVN) at three epochs spanning 2 months. This object was identi…
An SiO Maser Search off the Galactic Plane
S. Deguchi, T. Fujii, Y. Ita +9
We have searched for the SiO J=1--0 v= 1 and 2 maser lines at ~ 43 GHz in 277 2MASS/MSX/IRAS sources off the Galactic plane (|b|> 3 deg), which resulted in 119 (112 new) detections…
SiO Maser Survey of the Inner Bar of the Galactic Bulge
Takahiro Fujii, Shuji Deguchi, Hideyuki Izumiura +3
We surveyed 291 MSX/2MASS infrared objects in the 7 x 2 deg area of the galactic center in the 43 GHz SiO J=1--0 v=1 and 2 maser lines, obtaining accurate radial velocities of 163…
SiO Maser Survey of IRAS Sources in the Inner Galactic Disk
S. Deguchi, T. Fujii, I. S. Glass +7
We have surveyed 401 color selected IRAS sources in the Galactic disk in the SiO J=1--0 v= 1 and 2 maser lines at 43 GHz, resulting in 254 (239 new) detections. The observed source…
Chemical composition of UV-bright star ZNG 4 in the globular cluster M13
S. Ambika, M. Parthasarathy, W. Aoki +4
We present a detailed model-atmosphere analysis of ZNG 4, a UV-bright star in the globular cluster M13. From the analysis of a high resolution () spectrum of th…
Observations of SiO Maser Sources within a Few Parsec from the Galactic Center
Shuji Deguchi, Takahiro Fujii, Makoto Miyoshi +1
Mapping and monitoring observations of SiO maser sources near the Galactic center were made with the Nobeyama 45-m telescope at 43 GHz. Rectangular mapping an area of approximately…
