Abstract:
Millimetre observations of IRAS selected red carbon stars are
presented. About 260 stars have been observed with SEST and IRAM in
the CO (1-0) and CO (2-1) lines and partially in HCN (1-0) and SiO
(3-2). An overall detection rate, in at least one line, of about 80%
is achieved. The survey represents the second largest survey for AGB
stars, and the largest ever for carbon stars. Two new detections in
SiO (3-2) in carbon stars are reported. When available, the SiO/HCN
and HCN/CO(1-0) line ratios are consistent with the ratios expected
for carbon stars.
Description:
The results of a large millimetre survey of infrared carbon stars is
presented. The Table provides the detailed outcome of the
observations. IRAS name, transition and molecule, velocity resolution,
rms noise, peak temperature, integrated intensity, central velocity
and expansion velocity are presented.
