The circumstellar envelope of VX Sgr

Astrophysics and Space Science, 1992
By use of the data for VLBI observation of SiO masrs, and MERLIN observation of H2O and OH masers of VX Sgr, we found that the SiO, H2O, OH 1665/7, OH 1612 masers occur on a few separated shells, and the order of magnitude of the radii of their corresponding shells is 1014, 1015, 1016 cm, respectively.

Chemistry in Expanding Circumstellar Envelopes

1988
This review is concerned with the chemistry occurring in the. expanding envelopes around cool, late-type stars. We show that, although many different chemical processes help determine the overall chemical composition of such envelopes, the detailed composition, as evidenced by the many molecules detected at radio wavelengths, is best explained by a ...
