|Title:||Exact relativistic static charged dust discs and non-axisymmetric structures|
|Abstract:||The well-known 'displace, cut and reflect' method used to generate discs from given solutions of Einstein field equations is applied to the superposition of two extreme Reissner-Nordstrom black holes to construct discs made of charged dust and also non-axisymmetric planar distributions of charged dust on the z = 0 plane. They are symmetric with respect to two or one coordinate axes, depending on whether the black holes have equal or unequal masses, respectively. For these non-axisymmetric distributions of matter we also study the effective potential for geodesic motion of neutral test particles.|
