J/A+A/285/247 Molecules in O- and C-rich envelopes (Bujarrabal+ 1994)

ADC_Keywords: Radio lines ; Abundances ; Stars, late-type
Keywords: stars: abundances - stars: circumstellar matter - stars: late type -
stars: AGB, post-AGB - radiolines: stars
Description:
Observations of 10 microwave transitions of the molecules SiO, HCN,
HNC, SiS, HC_3_N, CS, SO, and ^13^CO are presented in a total sample
of 47 evolved stars. The studied sources are mainly O- and C-rich
standard AGB stars, as well as O-rich red supergiants, S-type stars,
protoplanetary nebulae and detached envelopes. We also take into
account observations of these transitions, as well as of ^12^CO J=1-0,
from the literature.
The observations were carried out during May and September 1991 and
June 1992 with the IRAM 30-m radiotelescope at Pico de Veleta (Spain);
the resolution is 1MHz for 3mm data (100GHz) and 2 MHz for 2 and 1mm
data (150 to 300GHz).
