Scientific paper
It is noted that in emitting gravitational waves, a binary star loses energy associated with orbital motion; as a consequence, the distance between the components decreases and the rotational velocity of the system increases. The influence of these factors on the evolution of binary stars is considered. A description is given of the way in which the components draw closer to each other until one of them fills its Roche lobe. If the volume of this lobe is sufficiently large, this component begins to lose matter as a result of gravitational interaction. The matter given up by the component filling the Roche lobe forms a stream of gas which moves toward the other, smaller component. Since the matter in the gas stream possesses angular momentum, a rotating gaseous disk or accretion disk is formed around this second component. The matter in the disk gradually loses its angular momentum and becomes part of the component.
