Inhomogeneities in molecular layers of Mira atmospheres
M. Wittkowski, D. A. Boboltz, M. Ireland +7
We obtained K-band spectro-interferometric observations of the Miras R Cnc, X Hya, W Vel, and RW Vel with a spectral resolution of 1500 using the VLTI/AMBER instrument. We obtained…
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…
Coordinated AMBER and MIDI observations of the Mira variable RR Aql
Iva Karovicova, Markus Wittkowski, David A. Boboltz +1
We have used near- and mid-infrared interferometry to investigate the pulsating atmosphere and the circumstellar environment of the Mira variable RR Aql. Observations were taken wi…
