Scientific paper

A molecular line search in the range between 85 and 89 GHz has been performed in the circumstellar envelope of 11 evolved stars using the 45 m telescope at Nobeyama Radio Observatory equipped with an acoustooptical spectrometer with a 2 GHz bandwidth. Emissions of 29SiO, 28SiO, HCN, H13CN, HC5N, HCO+, C2H, C4H, and C3N have been observed. The authors have detected the ground-state 29SiO J = 2-1 maser in several stars. They have also detected HCN emission in VY CMa, an oxygen-rich star.
