The energy of a doublestar system and its distribution.
Abstract
Hu Ning's expression of pseudoenergymomentum tensor density for the gravitational field is used to obtain a regular result for the energy of a doublestar system. But the distribution of this energy in space cannot be determined uniquely and its distribution laws are essentially identical to those of Schwarzschild external field of an isolated static star. If it is assumed that the gravitational field produced by the source matter no longer possesses gravitational mass, then the value of n in that expression can be determined along with the distribution of field energy.
