Upper limits for gravitational energy emitted during collisions.
Conservation laws applied to relativistic rotating disks.
Abstract
We discuss inelastic collisions of two rotating disks by using the conservation laws for baryonic mass and angular momentum. In particular, we formulate conditions for the formation of a new disk after the collision and calculate the total energy loss to obtain upper limits for the emitted gravitational energy.
