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…
Evidence of a substellar companion to AB Dor C
J. B. Climent, J. P. Berger, J. C. Guirado +5
Studies of fundamental parameters of very low-mass objects are indispensable to provide tests of stellar evolution models that are used to derive theoretical masses of brown dwarfs…
Tomography of cool giant and supergiant star atmospheres II. Signature of convection in the atmosphere of the red supergiant star Cep
K. Kravchenko, A. Chiavassa, S. Van Eck +4
Red supergiants are cool massive stars and are the largest and the most luminous stars in the universe. They are characterized by irregular or semi-regular photometric variations,…
Constraining stellar parameters and atmospheric dynamics of the carbon AGB star V Oph
Gioia Rau, Keiichi Ohnaka, Markus Wittkowski +2
Molecules and dust produced by the atmospheres of cool evolved stars contribute to a significant amount of the total material found in the interstellar medium. To understand the me…
Surface imaging of cool evolved stars in the era of the ELT
M. Wittkowski, A. Chiavassa, S. Höfner +1
Cool evolved stars are the main source of chemical enrichment of the interstellar medium. Understanding their mass loss offers a unique opportunity to study the cycle of matter. We…
Cool, evolved stars: results, challenges, and promises for the next decade
Gioia Rau, Rodolfo Montez, Kenneth G. Carpenter +27
Cool, evolved stars are the main source of chemical enrichment of the interstellar medium (ISM), and understanding their mass loss and structure offers a unique opportunity to stud…
