A binary system consists of two stars of equal mass m orbiting each other in a circular orbit under the influence of gravitational forces. The period of the orbit is T. At t= 0, the motion is stopped and the stars are allowed to fall towards each other. After what time t, expressed in terms of T, do they collide? x*dx -1 Va - x? va - x 2 +-sin Va 2
