Energy Levels of Electron Near Kerr Black Hole

In this paper, we investigated the energy levels of electron near micro-Kerr black hole under the approximation condition a ≪ GM /c2, and got some interest results.

A Possible Experimental Test on Five-Dimensional Gravitation Theory of Complex Field

By appropriately choosing additional dimensions of space-time, the mass spectrum of mesons is obtained, and the calculated results agree with the experimental data.

Energy Radiation of the Active Galactic Nuclei

In the Hellings–Nordtvedt theory, we obtain some expressions of energy radiation and mass defect effect for a kind of the active galactic nuclei, which is meaningful to calculating the energy radiation in the procession of forming this kind of celestial bodies. This calculation can give some interpretation for energy source of the jet from the active galactic nuclei.

Cosmological Constant and Stability of the Cosmological Models

The importance of cosmological constant for the cosmological models is given. The variations of the cosmological model for parameters and were discussed respectively. Near , the cosmological model is unstable with the change of , and near , the cosmological model is unstable with the change of . So when we consider the stable cosmological model, we must consider the nonzero cosmological constant.

Einstein-Maxwell Field of the Central Mass

We have obtained the exact solution of the Einstein-Maxwell equations outside the central mass with magnetic moment and, at the same time, we have investigated their asymptotic properties.

Gravitational Properties of an Accelerating Celestial Body with a Large Number of Monopoles

For the celestial body with electric and magnetic charge (a large number of magnetic monopoles), solving Einstein-Maxwell equations with the cosmological constant, we have reached a new metric and the Maxwell tensor, and discussed the effect of magnetic charge q and accelerationa for the kind of celestial body. Some new results have been obtained.

Gravitational Effects Near the Kerr-Newman Black Hole

We have reached a solution of the Dirac equation and the energy spectrum of electrons in the gravitational field of the Kerr-Newman black hole. The results are interesting in astrophysics for observations of the black hole.

The electron in the gravitational field of the Kerr black hole

We investigate the electronic energy levels in the field of the micro-Kerr black hole under the approximation condition a<<GM/c2 and obtain some interesting results.

Massive scalar particle in the gravitational field of a microcosmic black hole

The finite motion of a massive scalar particle in the gravitational field of a microcosmic black hole with weak relativistic approximation is discussed. In the Schwarzschild field, using the condition for balance σ = 0, we obtain the relation between the produced and captured amplitudes for particles. In the Kerr field we show that the attenuation depends on the moment of the black hole and the attenuation process becomes an exciting one when ω < mdh.
