Аннотация доклада:
Our seven-year long photometric and spectroscopic monitoring of CI Cam reveals the low amplitude light variation with a period of 19.41+/-0.02 day and strong Doppler shifts in the He II 4686 A emission line, phased with this period. The source of this emission moves on an elliptical (e=0.62) orbit around massive (M>=12 Msun) B4 III-V[e] star. It is very likely that the fast moving companion is a white dwarf surrounded by an accretion disk.
