Destroying Kaluza-Klein and Kerr-Newman black holes
Haryanto M. Siahaan, Paulus C. Tjiang
We investigate the destroying of charged and rotating black holes in Einstein-Maxwell-(dilaton) theory. We show that a test particle with some appropriate properties in the black h…
Rotating and charged Taub-NUT-(A)dS spacetimes on a 3-brane
Haryanto M. Siahaan
We construct novel solutions to the effective Einstein equation with four dimensional cosmological constant on a 3-brane in Randall-Sundrum II scenario. The charged solution is obt…
Gravitoelectromagnetism in Teleparallel Equivalent of General Relativity: A New Alternative
Kian Ming, Triyanta, J. S. Kosasih
Spaniol and Andrade introduced grvitoelectromagnetism in TEGR by considering superpotentials, times the determinant of tetrads, as the gravitoelectromagnetic fields. However, since…
Analytical Study of a Kerr-Sen Black Hole and a Charged Massive Scalar Field
Canisius Bernard
It is reported that Kerr-Newman and Kerr-Sen black holes are unstable to perturbations of charged massive scalar field. In this paper, we study analytically the complex frequencies…
Stationary Charged Scalar Clouds around Black Holes in String Theory
Canisius Bernard
It was reported that Kerr-Newman black holes can support linear charged scalar fields in their exterior regions. These stationary massive charged scalar fields can form bound state…
