Scientific paper

It is proposed that an exploding supermassive star in the nucleus of a galaxy can be a trigger and energy source for double radio sources. Detailed computations for the propagation of the shock front in an axially symmetric oblate density distribution are made on the assumption of a Gaussian density profile for the inner regions of the galaxy. The method of Laumbach and Probstein (1969), extended by Sakashita (1971), is used to obtain the differential equation for the shock front. It is shown that the shock front becomes prolate due to the steep density gradient of the interstellar material parallel to the axis. The material is ejected along the axis of rotation in the form of two antiparallel plasma jets.
