Abstract:
We surveyed 401 color-selected IRAS sources in the galactic disk in
the SiO J=1-0, v=1 and 2 maser lines at 43GHz, resulting in 254 (239
new) detections. The observed sources lie mostly in a strip of the
inner galactic disk with boundaries -10°<l<40° and |b|<3°.
This survey provides radial velocities of inner-disk stars for which
optical measurements cannot be made due to interstellar extinction.
Description:
Simultaneous observations in the SiO J=1-0, v=1 and 2 transitions at
43.122 and 42.821GHz, respectively, were made with the 45-m radio
telescope at Nobeyama during the period 1997 January-2003 May.
