DEATHSTAR: Nearby AGB stars with the Atacama Compact Array II. CO envelope sizes and asymmetries: The S-type stars
M. Andriantsaralaza, S. Ramstedt, W. H. T. Vlemmings +13
We aim to constrain the sizes of the CO circumstellar envelopes (CSEs) of 16 S-type stars, along with an additional 7 and 4 CSEs of C-type and M-type AGB stars, respectively. We ma…
Detection of highly excited OH towards AGB stars: A new probe of shocked gas in the extended atmospheres
T. Khouri, L. Velilla-Prieto, E. De Beck +5
We report the detection and investigate the properties of high-excitation lambda-doubling line emission of hydroxyl (OH) detected towards three asymptotic giant branch (AGB) stars…
High-resolution observations of gas and dust around Mira using ALMA and SPHERE/ZIMPOL
T. Khouri, W. H. T. Vlemmings, H. Olofsson +4
The outflows of oxygen-rich asymptotic giant branch (AGB) stars are thought to be driven by radiation pressure by photon scattering on grains with sizes of tenths of microns. The d…
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…
