Infrared interferometric three-dimensional diagnosis of the atmospheric dynamics of the AGB star R Dor with VLTI/AMBER
Keiichi Ohnaka, Gerd Weigelt, Karl-Heinz Hofmann
The mechanism of mass loss in late evolutionary stages of low- and intermediate-mass stars is not yet well understood. Therefore, it is crucial to study the dynamics of the region…
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…
Exploring the innermost dust formation region of the oxygen-rich AGB star IK~Tau with VLT/SPHERE-ZIMPOL and VLTI/AMBER
Christian Adam, Keiichi Ohnaka
Low- and intermediate-mass stars at the asymptotic giant branch (AGB) are known to be prevalent dust providers to galaxies. However, the mechanisms responsible for the formation an…
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…
