The prediction of next outburst on GRS 1915+105

摘要：

Since 1994 them have been five major outbursts with corresponding superluminal motion observed in microquasar GRS 1915+105. This paper shows that interval between two outbursts is approximately 3.5 years. The origin of the periodicity can be interpreted in term of the precession resulting in the torque induced by the gravitation field of the companion star. The assumption can be consistent with the measurement of binary parameter as well as the magnitude of proper motion of GRS 1915+ 105. It is predicted that the next outburst should be Dec 2007 to Oct 2008.
