The extended molecular envelope of the asymptotic giant branch star Gruis as seen by ALMA II. The spiral-outflow observed at high-angular resolution
L. Doan, S. Ramstedt, W. H. T. Vlemmings +8
The AGB star Gruis has a known companion (at a separation of ~400 AU) which cannot explain the strong deviations from the spherical symmetry of the CSE. Recently, hydrodyna…
Photodissociation of CO in the outflow of evolved stars
Maryam Saberi, Wouter Vlemmings, Elvire De Beck
Ultraviolet (UV) photodissociation of CO controls the abundances and distribution of CO and its photodissociation products. This significantly influences the gas-phase chemistry in…
Astro2020 Science White Paper: The fundamentals of outflows from evolved stars
E. De Beck, M. L. Boyer, V. Bujarrabal +16
Models of the chemical evolution of the interstellar medium, galaxies, and the Universe rely on our understanding of the amounts and chemical composition of the material returned b…
Precision Analysis of Evolved Stars
Stephen Ridgway, Rachel Akeson, Ellyn Baines +20
Evolved stars dominate galactic spectra, enrich the galactic medium, expand to change their planetary systems, eject winds of a complex nature, produce spectacular nebulae and illu…
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…
Rotation of the asymptotic giant branch star R Doradus
W. H. T. Vlemmings, T. Khouri, E. De Beck +7
High resolution observations of the extended atmospheres of asymptotic giant branch (AGB) stars can now directly confront the theories that describe stellar mass loss. Using Atacam…
