The abundance of SiS in circumstellar envelopes around AGB stars
F. L. Schoeier, J. Bast, H. Olofsson +1
New SiS multi-transition (sub-)millimetre line observations of a sample of AGB stars with varying photospheric C/O-ratios and mass-loss rates are presented. A combination of low- a…
Properties of detached shells around carbon stars: Evidence of interacting winds
F. L. Schoeier, M. Lindqvist, H. Olofsson
The nature of the mechanism responsible for producing the spectacular, geometrically thin, spherical shells found around some carbon stars has been an enigma for some time. Based o…
Probing the inner wind of AGB stars: Interferometric observations of SiO millimetre line emission from the oxygen-rich stars R Dor and L2 Pup
F. L. Schoeier, H. Olofsson, T. Wong +2
High angular resolution Australia Telescope Compact Array (ATCA) observations of SiO `thermal' millimetre line emission towards the two oxygen-rich, low mass loss rate AGB stars R…
Australia Telescope Compact Array imaging of circumstellar HCN line emission from R Scl
T. Wong, F. L. Schoeier, M. Lindqvist +1
We present radio-interferometric observations of HCN J=1-0 line emission from the carbon star R Scl, obtained with the interim 3-mm receivers of the Australia Telescope Compact Arr…
Odin observations of H2O in the Galactic Centre
Aa. Sandqvist, P. Bergman, J. Black
The Odin satellite has been used to detect emission and absorption in the 557-GHz H2O line in the Galactic Centre towards the Sgr A* Circumnuclear Disk (CND), and the Sgr A +20 km/…
`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…
