Initial data for a deformed isolated horizon
Original language description
Within the isolated horizon formalism, we investigate a static axisymmetric space-time of a black hole influenced by matter in its neighborhood. To illustrate the role of ingredients and assumptions in this formalism, we first show how, in spherical symmetry, the field equations and gauge conditions imply the isolated horizon initial data leading to the Schwarzschild space-time. Then, we construct the initial data for a static axisymmetric isolated horizon representing a deformed black hole. The space-time description in the Bondi-like coordinates is then found as a series expansion in the vicinity of the horizon. To graphically illustrate this construction, we also find a numerical solution for a black hole deformed by a particular analytic model of a thin accretion disk. We also discuss how an accretion disk affects the analytical properties of the horizon geometry.
