Rotating charged black hole solution in heterotic string theory

Abstract

We construct a solution of the classical equations of motion arising in the low energy effective field theory for heterotic string theory. This solution describes a black hole in four dimensions carrying mass M , charge Q and angular momentum J. The extremal limit of the solution is discussed.

Microscopic formulation of black holes in string theory

“…A way of generating charged solutions (see, e.g., [229,230,231] for details) is to unwrap the above solution in five non-compact dimensions, perform a boost in the 0-5 plane (which is a symmetry of the non-compact theory), and compactify the new x ′ 5 direction to get a charged (RN) black hole in four non-compact dimensions. The momenta should transform as…”

Kerr-Sen dilaton-axion black hole lensing in the strong deflection limit

“…In 1992 Sen [53] was able to find a charged, stationary, axially-symmetric solution [58] of the field equations by using target space duality, applied to the classical Ker solution. The line element of this solution can be written, in generalized Boyer-Linquist coordinates [55], as…”

Erratum: Hawking radiation from dilatonic black holes via anomalies [Phys. Rev. D75, 064029 (2007)]

“…The Kerr-Sen black hole [18] is a solution to the lowenergy effective action in heterotic string theory. The action containing a three-form (axion) field H and a dilaton field φ coupled to a U (1) gauge field F reads off [18,19] …”

“…Since the dilatonic black holes [14,15,16,17,18] obtained from the low energy effective field theory have qualitatively different properties from those in ordinary Einstein gravity, it is necessary and helpful to study the thermal properties of these black holes via the anomalous point of view. In this paper, motivated by RobinsonWilczek's recent viewpoint, we study Hawking radiation from the static, spherically symmetric dilatonic black holes with arbitrary coupling constant, and that from the rotating Kaluza-Klein and Kerr-Sen dilatonic black holes [19] via gauge and gravitational anomalies.…”
