Abstract:
We have searched the literature for all observations of the
12CO(1-0), 12CO(2-1), and HCN(1-0) lines in circumstellar
envelopes of late type stars published between January 1985 and
September 1992. We report data for 1361 observations (stellar
velocity, expansion velocity, peak intensity, integrated area, noise
level). This CO-HCN sample now contains 444 sources. 184 are
identified as oxygen-rich, 205 as carbon-rich, and there are 9 S
stars. About 85% of the sources are AGB stars. There are 32 planetary
nebulae and about thirty post-AGB stars candidates. Besides results of
millimeter observations, we also list identifications, coordinates,
IRAS data, chemical and spectral types for every source. For AGB
stars, we have estimated (or compiled) bolometric fluxes and distances
for 349 sources, and mass loss rates deduced from CO results for 324
sources, taking into account the influence of the CO photodissociation
radius. We also list mass loss rates derived from detailed models of
CO emission which we could find in the literature.
