Аннотация доклада:
V4641 Sgr is the detached binary system containing a black hole candidate of 9 solar masses and B9-A0III secondary star, with an orbital period of 2.817 days. We restore its photometric history since 1960. During X-Ray outbursts an increase in the optical brightness was up to 5 magnitudes and the outflow of relativistic jets was ovserved in radio range at 1999 outburst. The ellipsoidal effect of 0.4 star magnitude is observed in optical star. In May 2007 an appearance of reflection effect was detected. After our report SWIFT detected weak and variable X-Ray radiation.
