This paper is divided into four parts. In part A, some general considerations about gravitational radiation are followed by a treatment of the scalar wave equation in the manner later to be applied… Expand

THE emission of gravitational waves from a finite isolated axially symmetrical material system in otherwise empty space has been investigated by consideration of the metric : Einstein vacuum field… Expand

The field equations of general relativity areapplied to pressure-free spherically symmetrical systemsof particles. The equations of motion are determinedwithout the use of approximations and are… Expand

POLARIZED plane gravitational waves were first discovered by N. Rosen1, who, however, came to the conclusion that such waves could not exist because the metric would have to contain certain physical… Expand
