`Thermal' SiO radio line emission towards M-type AGB stars: a probe of circumstellar dust formation and dynamics
D. Gonzalez Delgado, H. Olofsson, F. Kerschbaum +3
An extensive radiative transfer analysis of circumstellar SiO `thermal' radio line emission from a large sample of M-type AGB stars has been performed. The sample contains 18 irreg…
Mass loss rates of a sample of irregular and semiregular M-type AGB-variables
H. Olofsson, D. Gonzalez Delgado, F. Kerschbaum +1
We have determined mass loss rates and gas expansion velocities for a sample of 69 M-type irregular (IRV; 22 objects) and semiregular (SRV; 47 objects) AGB-variables using a radiat…
Imaging of detached shells around the carbon stars R Scl and U Ant through scattered stellar light
D. Gonzalez Delgado, H. Olofsson, H. E. Schwarz +2
We present the first optical images of scattered light from large, detached gas/dust shells around two carbon stars, R Scl and U Ant, obtained in narrow band filters centred on the…
