Electric and dilatonic fields of a charged massive particle at rest in the field of a charged dilaton black hole
Abstract We study linear-perturbation equations for the two-body system of a charged dilaton black hole, of which dilaton coupling constant is $$\alpha $$ α , and a static particle with mass m, electric charge q, and dilatonic charge $$\beta m$$ β m . We find that a consistent condition for the coup...

| description | Abstract We study linear-perturbation equations for the two-body system of a charged dilaton black hole, of which dilaton coupling constant is $$\alpha $$ α , and a static particle with mass m, electric charge q, and dilatonic charge $$\beta m$$ β m . We find that a consistent condition for the coupled equations corresponds to the equilibrium condition of the test particle. The expressions of classical fields are given in closed analytical formulas in the most interesting case with $$\beta =\alpha $$ β = α . We examine the electrical field around a charged dilaton black hole especially in the limit of the maximum electric charge and we find the electric Meissner effect which has been found for the Reissner–Nordström black hole in the Einstein–Maxwell system. |
