II. - INTERACTIONS GRANITATIONELLES EN ASTROPHYSIQUE / GRAVITATIONAL ENERGY YIELDS

Hermann Bondi

The phase of slow gravitational contraction of a spherical body, with its control by radiation from the body, is contrasted with the dynamical collapse that occurs when gravitation is not balanced by pressure forces. It is shown that in general relativity contraction inevitably changes to collapse when the gravitational potential energy becomes a significant fraction of rest mass. Therefore gravitation can only convert at most about 1 % of rest mass into radiation.
