A combined rotating charged dust-surface layer source for the McCrea electrovacuum
Georgiou, A. (2003)The McCrea electrovacuum is one of the few known stationary cylindrically symmetric solutions of the Einstein-Maxwell field equations. In the purely gravitational case in which the electromagnetic field is absent, a source ... -
The electromagnetic field in rotating coordinates
Georgiou, A. (1988)The electromagnetic field equations in rotating coordinates obtained by various authors, are based on incorrect expressions for the divergence and curl operators and the electromagnetic spatial vectors. This is a serious ... -
Perfectly conducting rapidly rotating sphere and pulsar electrodynamics
Georgiou, A. (2005)We consider a perfectly conducting fluid with spherical boundary, rotating with constant angular velocity in an electromagnetic field. We then obtain, in the framework of special relativity, the exact forms of the equations ... -
A rapidly rotating perfectly conducting sphere and the electrodynamics of a neutron star
Georgiou, A. (2008) -
Stationary axially symmetric rigidly rotating charged dust
Georgiou, A. (2001)We obtain three stationary axially symmetric solutions of the Einstein–Maxwell field equations for rigidly rotating charged dust in a force–free electromagnetic field. The first solution, expressed in terms of Bessel ... -
A virial theorem for rotating charged perfect fluids in general relativity
Georgiou, A. (2003)We obtain an exact form of the virial theorem in general relativity, which is sufficiently general to be applied to charged, conducting, rotating perfect fluids in electromagnetic and gravitational fields. The case of ...
