The rapidly evolving hypergiant IRC+10420: High-resolution bispectrum speckle-interferometry and dust-shell modelling
T. Bloecker, Y. Balega, K. -H. Hofmann +3
The hypergiant IRC+10420 is a unique object for the study of stellar evolution since it is the only object that is believed to be witnessed in its rapid transition from the red sup…
Bispectrum speckle interferometry of the Orion Trapezium stars: detection of a close (33 mas) companion of Theta1 Ori C
Gerd Weigelt, Yuri Balega, Thomas Preibisch +3
We present bispectrum speckle interferometry observations with the SAO 6 m telescope of the four brightest stars in the Orion Trapezium. Diffraction-limited images with an unpreced…
High-resolution speckle masking interferometry and radiative transfer modeling of the oxygen-rich AGB star AFGL 2290
A. Gauger, Y. Y. Balega, P. Irrgang +2
We present the first diffraction-limited speckle masking observations of the oxygen-rich AGB star AFGL 2290. The data was obtained with the Russian 6m SAO telescope. At the wavelen…
