S-branes from unbalanced black diholes
Abstract
Description
We construct new non-singular and time-dependent solutions from the black diholes with unbalanced magnetic charge. These solutions are constructed by the double Wick rotation with the analytic continuation of the mass or NUT-parameter of unbalanced black diholes. In the limit of balanced magnetic charge, our solutions reduce to the S-brane solution obtained from the black diholes discussed by Jones et al. . We study the behaviors of metric components and discuss the s-charge over a constant time-slice. From the properties of the solutions, we find that our solutions correspond to the S-brane type solutions.
