On the Optical Spectrum of Mu Cephei
High resolution spectra of M-type supergiant μ Cep are analyzed. The movements in the atmosphere of this star are highly supersonic and variable with depth. The lines forming in deeper layers show the widths corresponding to 30 kms−1. The lines forming in outer layers are much wider, 50 kms−1. At th...
