We apply the Keski-Vakkuri, Kraus and Wilczek (KKW) generalized analysis to a magnetic stringy black hole solution to compute its temperature and entropy. The solution that we choose in the Einstein-dilaton-Maxwell theory is the dual solution known as the magnetic black hole solution. Our results show that the expressions of the temperature and en-tropy of… (More)
We calculate the energy distribution of an anisotropic model of universe based on the Bianchi type I metric in the Tolman's prescription. The energy due to the matter plus gravitational field is equal to zero. This result agrees with the results of Banerjee and Sen and Xulu. Also, our result supports the viewpoint of Tryon and Rosen.
We calculate the energy distribution in a static spherically symmetric nonsingular black hole space-time by using the Tolman's energy-momentum complex. All the calculations are performed in quasi-Cartesian coordinates. The energy distribution is positive everywhere and be equal to zero at origin. We get the same result as obtained by Y-Ching Yang by using… (More)
It is well-known that one of the most interesting and challenging problems of General Relativity is the energy and momentum localiza-tion. There are many attempts to evaluate the energy distribution in a general relativistic system. One of the methods used for the energy and momentum localization is the one which used the energy-momentum complexes. After… (More)
We use Møller's energy-momentum complex in order to explicitly compute the energy and momentum density distributions for an exact solution of Einstein's field equations with a negative cosmological constant minimally coupled to a static massless scalar field in a static, spherically symmetric background in (2 + 1)-dimensions.
We calculate the energy distribution of a charged regular black hole by using the energy-momentum complexes of Einstein and Møller.
We calculate the energy distribution of a dyonic dilaton black hole by using the Tolman's energy-momentum complex. All the calculations are performed in quasi-Cartesian coordinates. The energy distribution of the dyonic dilaton black hole depends on the mass M , electric charge Q e , magnetic charge Q m and asymptotic value of the dilaton Φ 0. We get the… (More)
We calculate the energy distribution of a charged black hole solution in heterotic string theory in the Møller prescription.
We provide a new electromagnetic mass model admitting non static conformal symmetry. We conclude that the pressure and density failed to be regular at the origin but gravitational mass is always positive and vanishes in the limit r → 0 i.e. it does not have to tolerate the problem of sin-gularity. Further, we match interior metric with the exterior… (More)
