Abstract

The results of long-time spectral monitoring of the Be Herbig star IL Cep A are presented. It is shown that hydrogen emission lines are formed in the disk, which is formed only around one of the components of the binary system. Orbital elements were calculated in the model of a spectroscopic - binary system with a period of 3550 28 days. It was estimated fundamental parameters of individual components of the system. It is assumed that the secondary component of the system is a young star, which is at the initial stage of evolution.
