Abstract:
We present the results of an SiO maser survey for color-selected IRAS
sources in the area 40°<l<70° and |b|<10° in the SiO
J=1-0, v=1 and 2 transitions (∼43GHz). We detected 134 out of 272
observed sources in SiO masers; 127 were new detections. A systematic
difference in the detection rates between SiO and OH maser searches
was found.
Description:
Simultaneous observations in 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 from 2000 April to 2001 March.
