Wahlquist Metric Revisited
M. Hortaçsu
Here we continue studying the Wahlquist metric. We know that the wave equation written for a zero mass scalar particle in the background of this metric gives Heun type solutions. T…
A massless scalar particle coupled to the Wahlquist metric
T. Birkandan, M. Hortacsu
We study the solutions of the wave equation where a massless scalar field is coupled to the Wahlquist metric, a type-D solution. We first take the full metric and then write simpli…
The radial Teukolsky equation for Kerr-Newman-de Sitter geometry: Revisited
M. Hortacsu
We use Heun type solutions given in \cite{Suzuki} for the radial Teukolsky equation, written in the background metric of the Kerr-Newman-de Sitter geometry, to calculate the quasin…
The zero mass limit of Kerr and Kerr-(anti-)de Sitter space-times: Revisited
M. Hortacsu
We continue studying the zero mass limit of the Kerr- (Anti) de Sitter space-times by investigating the possibility of special values of the frequencies to have polynomial solution…
Exact solution of the wave equation of a scalar particle in the zero mass limit of Kerr and Kerr-(anti-)de-Sitter space-times
T. Birkandan, M. Hortaçsu
Heun-type exact solutions emerge for both the radial and the angular equations for the case of a scalar particle coupled to the zero mass limit of both the Kerr and Kerr-(anti)de-S…
Heun-type solutions for Schwarzschild metric with electromagnetic fields
T. Birkandan, M. Hortaçsu
We find confluent Heun solutions to the radial equations of two Halilsoy-Badawi metrics. For the first metric, we studied the radial part of the massless Dirac equation and for the…
