MULTIWAVELENGTH SPECTROSCOPY OF THE STABLE SHELL STAR HD-193182

Abstract

HD 193182 is one of the most interesting ''stable shell stars'' and presents stable shell features which seems to be constant over decades. In this research we analyzed optical, ultraviolet and near-infrared spectra of this little-studied shell star. In the meantime we applied model calculations to the measured spectral parameters of HD 193182 in order to present a more complete view of its stellar and envelope characteristics.
