PostNewtonian Approximation of a Nonstationary Spherically Symmetric Star in Flat SpaceTime Theory of Gravitation
Abstract
Starting from a previously studied theory of gravitation in flat spacetime the postNewtonian approximation of the gravitational field of an nonstationary spherically symmetric star is derived. To the postNewtonian order the equations of motion and the conserved total energy of a collapsing star are given. Birkhoff's theorem holds to this accuracy.
