Observations of Mira stars with the IOTA/FLUOR interferometer and comparison with Mira star models
K. -H. Hofmann, U. Beckmann, T. Bloecker +16
We present K'-band observations of five Mira stars with the IOTA interferometer. The interferograms were obtained with the FLUOR fiber optics beam combiner, which provides high-acc…
Diffraction-limited speckle interferometry and modeling of the circumstellar envelope of R CrB at maximum and minimum light
K. Ohnaka, Y. Balega, T. Bloecker +6
We present the first speckle interferometric observations of R CrB, the prototype of a class of peculiar stars which undergo irregular declines in their visible light curves. The o…
Speckle interferometry and radiative transfer modelling of the Wolf-Rayet star WR 118
B. Yudin, Y. Balega, T. Bloecker +3
WR 118 is a highly evolved Wolf-Rayet star of the WC10 subtype surrounded by a permanent dust shell absorbing and re-emitting in the infrared a considerable fraction of the stellar…
A multi-wavelength study of the oxygen-rich AGB star CIT 3: Bispectrum speckle interferometry and dust-shell modelling
K. -H. Hofmann, Y. Balega, T. Bloecker +1
(abridged) CIT 3 is an oxygen-rich long-period variable evolving along the AGB and one of the most extreme infrared AGB objects. We present the first bispectrum speckle-interferome…
Evolution on the AGB and beyond: On the formation of H-deficient post-AGB stars
T. Bloecker
The evolution on the AGB and beyond is reviewed with respect to the origin of Wolf-Rayet central stars. We focus on thermal pulses due to their particular importance for the evolut…
Bispectrum speckle interferometry observations and radiative transfer modelling of the red supergiant NML Cyg: Multiple dust-shell structures evidencing previous superwind phases
T. Bloecker, Y. Balega, K. -H. Hofmann +1
(abridged) NML Cyg is a highly evolved OH/IR supergiant and supposed to be among the most luminous supergiants in the galaxy. We present the first diffraction limited 2.13micron ob…
