Scientific paper

A supermassive binary black hole model for the blazar OJ287 was proposed by Sillanpaa et al. (ApJ 325, 628, 1988) on the basis of its historical light curve, which shows optical outbursts with a periodicity of about 11.9 years. This model also predicted the next outburst in fall 1994 on the basis of the idea that tidally induced transfer of matter in the accretion disk of the primary is responsible for the increased output of the relativistic jet. The outburst was also observed as predicted. Here we will show that the outburst periodicity has been amazingly strict during the last 4-5 cycles. The only known astronomical system that causes such a strict periodicity is a binary system.
