The wonderful complexity of the Mira AB system

S. Ramstedt, S. Mohamed, W. H. T. Vlemmings +17

We have mapped the CO(3-2) line emission around the Mira AB system at 0.5 resolution using the Atacama Large Millimeter/submillimeter Array (ALMA). The CO map shows amazing complex…

The detached dust shells around the carbon AGB stars R Scl and V644 Sco

Matthias Maercker, Sofia Ramstedt, Marcelo M. L. Leal-Ferreira +2

Detached shells are believed to be created during a thermal pulse, and constrain the time scales and physical properties of one of the main drivers of late stellar evolution. We ai…

The wind of W Hya as seen by Herschel. II. The molecular envelope of W Hya

T. Khouri, A. de Koter, L. Decin +18

The evolution of low- and intermediate-mass stars on the asymptotic giant branch (AGB) is mainly controlled by the rate at which these stars lose mass in a stellar wind. Understand…

Detailed modelling of the circumstellar molecular line emission of the S-type AGB star W Aquilae

T. Danilovich, P. Bergman, K. Justtanont +5

S-type AGB stars have a C/O ratio which suggests that they are transition objects between oxygen-rich M-type stars and carbon-rich C-type stars. As such, their circumstellar compos…

The wind of W Hya as seen by Herschel - I. The CO envelope

T. Khouri, A. de Koter, L. Decin +25

Asymptotic giant branch (AGB) stars lose their envelopes by means of a stellar wind whose driving mechanism is not understood well. Characterizing the composition and thermal and d…
