J, H, K spectro-interferometry of the Mira variable S Orionis
M. Wittkowski, D. A. Boboltz, T. Driebe +4
Aims: We present J, H, K interferometry with a spectral resolution of 35 for the Mira variable S Orionis. We aim at measuring the diameter variation as a function of wavelength tha…
The Mira variable S Ori: Relationships between the photosphere, molecular layer, dust shell, and SiO maser shell at 4 epochs
M. Wittkowski, D. A. Boboltz, K. Ohnaka +2
We present the first multi-epoch study that includes concurrent mid-infrared and radio interferometry of an oxygen-rich Mira star. We obtained mid-infrared interferometry of S Ori…
3D Radiative Transfer Modeling of Clumpy Dust Tori Around AGN
S. F. Hoenig, T. Beckert, K. Ohnaka +1
We present 3-dimensional radiative transfer models for clumpy dust tori around AGN. Our method combines Monte Carlo simulations of individual dust clouds with the actual 3-dimensio…
VLTI observations of AGB stars
M. Wittkowski, D. A. Boboltz, T. Driebe +1
We report on recent observations of AGB stars obtained with the VLT Interferometer (VLTI). We illustrate in general the potential of interferometric measurements to study stellar a…
