HD 193182 is one of the most interesting ''stable shell stars'' and pr
esents stable shell features which seems to be constant over decades.
In this research we analyzed optical, ultraviolet and near-infrared sp
ectra of this little-studied shell star. In the meantime we applied mo
del calculations to the measured spectral parameters of HD 193182 in o
rder to present a more complete view of its stellar and envelope chara
cteristics.
