The two NUT-like solutions of Ernst equation
- Department of Physics, Liaoning Normal University, Dalian (116029) (China)
By applying Ehlers transformation to Schwarzschild and Kerr solutions of Ernst equation and choosing the suitable coordinate transformations, the two NUT-like solutions, i.e., the so called NUT-Taub-like and the Kerr-NUT-like solutions are obtained which not only can, respectively, reduce to Schwarzschild and Kerr solutions when the parameter l{sup '}=0, but also can also reduce to the NUT-Taub metric and Kerr-NUT metric, respectively, when l{sup '} satisfies the some approximation. Meanwhile it is shown that in the NUT-Taub and Kerr-NUT solutions the range of value for the parameter l interpreted as the gravomagnetic monopole cannot be arbitrary and should be confined by mass of the source to vertical bar l vertical bar<<m. Furthermore, the differences in the geometrical structure between the NUT-Taub-like and NUT-Taub solutions are discussed and the physical properties of the horizons on the Kerr-NUT-like space-time are analyzed.
