Silicon and Sulphur in the Inner Envelope of IRC+10216of the interstellar UV field can initiate a complex photochemistry. These models use as input the abundances of parent species which are either set from observational data or from LTE abundances, which are valid in the photosphere, and which assume that the molecules pass through the inner layers of

Maser Mapping and Dust Properties of Red Supergiant Windsind is driven by radiation pressure on dust and the structure and kinematics of the masing regions reflect the dust properties. The unbeamed radius of water maser blobs, ~ 10. m, has been measured for the first time. The velocity gradient is used to derive the dust absorption coefficient which incre

Disks around Post-Main Sequence Binariesarbon-rich star with an oxygen-rich circumstellar envelope. The CO emission from both of these disks has a spike with a width near ~2 km s., indicating disk radii of 10. cm. The dust in such disks is therefore quite cold (near T ~ 50 K for the Red Rectangle) and may emit primarily at submillimeter w

UIR Bands in Carbon Star Spectraiolet radiation in order for the UIR bands to be excited. If, in addition to amorphous carbon and hydrogenated amorphous carbon (HAC) particles, PAHs are able to form in the outflows of cool carbon-rich stars (Cherchneff et al. 1991), then the weak UV radiation field from such stars would be unlikel
