The Variable Spectrum of the Yellow Hypergiant rho Cassiopeiae
We have analyzed high-resolution optical spectra of the cool hypergiant rho Cas covering a period 2 years. The aim of this analysis is to check the range of the effective temperature variations with the pulsation of the atmosphere, in order to study variable emission components in Hα, to investigate the splitting of metallic absorption lines and to
