Post-newtonian approximation of a nonstationary spherically symmetric star in flat space-time theory of gravitation

  • Walter Petry


Starting from a previously studied theory of gravitation in flat space-time the post-Newtonian approximation of the gravitational field of an nonstationary spherically symmetric star is derived. To the post-Newtonian order the equations of motion and the conserved total energy of a collapsing star are given. Birkhoff's theorem holds to this accuracy.
