AMBER : a near infrared focal instrument for the VLTI
Romain G. Petrov, Fabien Malbet, Andrea Richichi +3
AMBER is the General User near-infrared focal instrument of the Very Large Telescope interferometer. Its specifications are based on three key programs on Young Stellar Objects, Ac…
A quasi-time-dependent radiative transfer model of OH104.9+2.4
D. Riechers, Y. Balega, T. Driebe +4
We investigate the pulsation-phase dependent properties of the circumstellar dust shell (CDS) of the OH/IR star OH104.9+2.4 based on radiative transfer modeling (RTM) using the cod…
High-resolution near-infrared speckle interferometry and radiative transfer modeling of the OH/IR star OH 104.9+2.4
D. Riechers, Y. Balega, T. Driebe +3
We present near-infrared speckle interferometry of the OH/IR star OH 104.9+2.4 in the K' band obtained with the 6m telescope of the Special Astrophysical Observatory (SAO). At a wa…
Evidence for bipolar jets in late stages of AGB winds
D. Vinkovic, M. Elitzur, K. -H. Hofmann +1
Bipolar expansion at various stages of evolution has been recently observed in a number of AGB stars. The expansion is driven by bipolar jets that emerge late in the evolution of A…
Diffraction-limited bispectrum speckle interferometry and speckle polarimetry of the young bipolar outflow source S140 IRS1
D. Schertl, Y. Balega, T. Hannemann +3
We present bispectrum speckle interferometry and speckle polarimetry of the deeply embedded infrared bipolar outflow source S140 IRS1, a massive protostellar object in the L1204 mo…
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…
