On the energy of a charged dilaton black hole

TL;DR

This paper calculates the energy distribution of a dyonic dilaton black hole using Einstein's energy-momentum pseudotensor, revealing dependencies on mass, charges, and dilaton values, and compares results with previous studies.

Contribution

It provides a new calculation of energy distribution for dyonic dilaton black holes considering additional parameters and compares these with prior results.

Findings

Energy depends on mass, electric and magnetic charges, and dilaton value.

Results differ from previous studies by Virbhadra et al.

Highlights the role of dilaton in black hole energy distribution.

Abstract

Employing energy-momentum pseudotensor of Einstein, we obtian the energy distribution of a dyonic dilaton black hole. The energy distribution of this black hole depends on mass $ M $, electric charge $ Q_{e} $, magnetic charge $ Q_{m} $ and asymptotic values of the dilaton $ \phi_{0} $. We also mmake some comparisons between the results of Virbhadra et. al. and ours.
