Near-infrared spectro-interferometry of three OH/IR Stars with the VLTI/AMBER instrument
A. E. Ruiz-Velasco, M. Wittkowski, A. Wachter +2
We investigate the molecular and dusty environment of OH/IR stars in order to characterize the mass-loss process during the tip-AGB superwind phase. Employing the AMBER instrument…
Structure and shaping processes within the extended atmospheres of AGB stars
M. Wittkowski, D. A. Boboltz, I. Karovicova +4
We present recent studies using the near-infrared instrument AMBER of the VLT Interferometer (VLTI) to investigate the structure and shaping processes within the extended atmospher…
The extended atmospheres of Mira variables probed by VLTI, VLBA, and APEX
M. Wittkowski, D. A. Boboltz, C. de Breuck +9
We present an overview on our project to study the extended atmospheres and dust formation zones of Mira stars using coordinated observations with the Very Large Telescope Interfer…
