Reissner-Nordström Spacetimes  

In General > s.a. black holes; generalized reissner-nordström spacetimes.
> Note: The spelling is Reissner-Nordström, not Reissner-Nordstrøm [@ see Brill & Dray GRG(93)].
$ Def: A family of solutions of Einstein's equation representing a non-rotating black hole with non-zero electric charge, depending on the parameters M (mass) and Q = (Qe2 + Qm2)1/2 (electromagnetic charges) [c = 1], and line element

ds2 = −(1 − 2GM/r + GQ2 /r2) dt2 + (1 − 2GM/r + GQ2 /r2)−1 dr2 + r22 .

* Singularities: For Q2 > GM2, we get a naked singularity; For Q2 < GM2, a regular black-hole solution with two horizons, at r = r± = GM ± (G2M2GQ2)1/2 (from grr = 0), besides the true singularity at r = 0; For Q2 = GM2, the extreme case.
* Electromagnetic field:

if Qm = 0,  Aa = (Qe/r, 0, 0, 0),  F01 = −Qe/r2 ;   if Qe = 0,  Aa = (0, −Qm sin θ, 0, 0),  F23 Qmsin θ .

* Symmetries: The only conformal or projective vector fields it admits are its standard Killing vector fields [@ Hall CQG(00)].
* Fermat geometry: For P = 0, if q:= Q/M and d2:= 1−q2 (the horizon is at r/M = 1/d), then the Fermat geometry is non-hyperbolic for r/M > 1 + (d/2)2/3; One can get arbitrarily close to the horizon (> SS 1.12.1995).
