Abstract:
We have surveyed ∼400 known large-amplitude variables within 15' of
the galactic center in the SiO J=1-0 v=1 and 2 maser lines at 43GHz,
resulting in 180 detections. SiO lines were detected from 16 other
sources located within 20" of the program objects. The detection rate
of 48% is comparable to that in bulge IRAS surveys.
Description:
Simultaneous observations in the SiO J=1-0 v=1 and 2 and 2 transitions
at 42.122 and 42.821GHz, respectively, were made with the 45-m radio
telescope at Nobeyama during the periods of 2001 February-May, 2002
March-May, and 2003 May.
