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,…
Carbon stars with increased oxygen and nitrogen abundances: hydrostatic dust-free model atmospheres
Bernhard Aringer, Paola Marigo, Walter Nowotny +3
We have computed a grid of hydrostatic spherical COMARCS models for C stars covering metallicities from [Z/H]=0 to -2 and values of the carbon excess [C-O] from 6.41 to 9.15, plus…
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…
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…
Rings and filaments: The remarkable detached CO shell of U Antliae
F. Kerschbaum, M. Maercker, M. Brunner +11
Aims. Our goal is to characterize the intermediate age, detached shell carbon star U Antliae morphologically and physically in order to study the mass-loss evolution after a possib…
Large-scale environments of binary AGB stars probed by Herschel. II: Two companions interacting with the wind of pi1 Gruis
A. Mayer, A. Jorissen, C. Paladini +12
Context. The Mass loss of Evolved StarS (MESS) sample observed with PACS on board the Herschel Space Observatory revealed that several asymptotic giant branch (AGB) stars are surro…
Dusty shells surrounding the carbon variables S Scuti and RT Capricorni
M. Mecina, F. Kerschbaum, M. A. T. Groenewegen +8
For the Mass-loss of Evolved StarS (MESS) programme, the unprecedented spatial resolution of the PACS photometer on board the Herschel space observatory was employed to map the dus…
Large-scale environments of binary AGB stars probed by Herschel - I. Morphology statistics and case studies of R Aquarii and W Aquilae
A. Mayer, A. Jorissen, F. Kerschbaum +14
The Mass loss of Evolved StarS (MESS) sample offers a selection of 78 Asymptotic Giant Branch (AGB) stars and Red Supergiants (RSGs) observed with the PACS photometer on-board Hers…
