Scientific paper

Repeated spectroscopic observations have been made at medium dispersion of the egress phase of the VV Cep eclipsing binary system. The double emission profiles of H beta and H alpha showed characteristic variations. The blue emission component reappeared first followed by the red one. This agrees with the corresponding results obtained during the ingress phase. A rapidly rotating oblate envelope around the hot companion is proposed as a model for the emission region. The contact epochs of the different emission components allow conclusions on the morphology of the envelope.
