The Jets and Supercritical Accretion Disk in Ss433

This book describes and reviews observations and investigations of the unique object SS433 obtained after 23 years of studying the massive binary system. The main difference between SS433 and other known X-ray binaries is the action of a constant supercritical regime for the accretion of gas onto the relativistic star (most likely a black hole) which has led to the formation of a supercritical accretion disk and collimated relativistic jets. The properties of jets are to a large extent determined by their interaction with disk wind. The precession of the disk and jets as well as the eclipsing in the binary system make SS433 a unique laboratory for studies of mechanisms for the microquasar phenomenon. The author describes the main ideas and results emerging from studies of the formation of the jets and supercritical accretion disk in SS433.
