An Outbursting Protostar of the FU~Orionis type in the Cygnus OB7 Molecular Cloud
T. A. Movsessian, T. Khanzadyan, C. Aspin +5
Context: To follow the early evolution of stars we need to understand how young stars accrete and eject mass. It is generally assumed that the FU Orionis phenomenon is related to t…
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 Spectroscopy of the Yellow Hypergiant Rho Cassiopeiae from 1993 Through the Outburst of 2000-2001
A. Lobel, A. K. Dupree, R. P. Stefanik +7
We present an overview of the spectral variability of the peculiar F-type hypergiant Rho Cas, obtained from our long-term monitoring campaigns over the past 8.5 years with four spe…
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…
