Lfb. Torres et Ja. Souza, ELECTROMAGNETIC-RADIATION FROM A SOURCE AT THE CENTER OF A STATIC CHARGED DUST SPHERE, Astrophysics and space science, 204(1), 1993, pp. 1-8
Using Maxwell equations in a background metric discovered by Bonnor, w
hich describes the gravitational field generated by an optimally charg
ed dust ball, we calculate the external radiation field from an electr
ic dipole source at the center the ball. Possible applications to stel
lar mode 1 s are discussed in the conclusions.
