Extended view on the dust shells around two carbon stars
M. Mečina, B. Aringer, W. Nowotny +4
Stars on the asymptotic giant branch (AGB) lose considerable amounts of matter through their dust-driven stellar winds. A number of such sources have been imaged by Herschel/PACS,…
ALMA observations of the "fresh" carbon-rich AGB star TX Piscium. The discovery of an elliptical detached shell
Magdalena Brunner, Marko Mecina, Matthias Maercker +4
Aims. The carbon-rich asymptotic giant branch (AGB) star TX Piscium (TX Psc) has been observed multiple times during multiple epochs and at different wavelengths and resolutions, s…
Properties of dust in the detached shells around U Ant, DR Ser, and V644 Sco
M. Maercker, T. Khouri Silva, E. De Beck +3
Understanding the properties of dust produced during the asymptotic giant branch phase of stellar evolution is important for understanding the evolution of stars and galaxies. Rece…
Molecular line study of the S-type AGB star W Aquilae. ALMA observations of CS, SiS, SiO and HCN
Magdalena Brunner, Taissa Danilovich, Sofia Ramstedt +5
Context. With the outstanding spatial resolution and sensitivity of the Atacama Large Millimeter/sub-millimeter Array (ALMA), molecular gas other than the abundant CO can be observ…
An independent distance estimate to the AGB star R Sculptoris
M. Maercker, M. Brunner, M. Mecina +1
For the carbon AGB star R Sculptoris, the uncertain distance significantly affects the interpretation of observations regarding the evolution of the stellar mass loss during and af…
The circumstellar envelope around the S-type AGB star W Aql Effects of an eccentric binary orbit
S. Ramstedt, S. Mohamed, W. H. T. Vlemmings +9
The CO(J=3-2) emission from the CSE of the binary S-type AGB star W Aql has been observed at subarcsecond resolution using ALMA. The aim of this paper is to investigate the wind pr…
