Cosmological tests of generalized RS brane-worlds with Weyl fluid
László Á. Gergely, Zoltán Keresztes, Gyula M. Szabó
A class of generalized Randall-Sundrum type II (RS) brane-world models with Weyl fluid are confronted with the Gold supernovae data set and BBN constraints. We consider three model…
The luminosity-redshift relation in brane-worlds: II. Confrontation with experimental data
Gyula M. Szabó, László Á. Gergely, Zoltán Keresztes
The luminosity distance - redshift relation for a wide class of generalized Randall-Sundrum type II brane-world models with Weyl fluid is compared to the presently available supern…
Kepler Equation for the Compact Binaries under the Spin-spin Interaction
Zoltán Keresztes, Balázs Mikóczi
In this work we consider compact binaries on eccentric orbit under the spin-spin interaction. Using the post-Newtonian formalism, the binaries undergo a perturbed Keplerian motion.…
Generalized eccentric vs. true anomaly parametrizations in the perturbed Keplerian motion
Balázs Mikóczi, Zoltán Keresztes
The angular and the radial parts of the dynamics of the perturbed Kepler motion are separable in many important cases. In this paper we study the radial motion and its parametrizat…
On the luminosity-redshift relation in brane-worlds with cosmological constant
Botond Nagy, Zoltán Keresztes
In this paper we calculate the luminosity distance - redshift relation for a special type of flat Friedmann brane with cosmological constant. This special case is singled out by it…
The luminosity-redshift relation in brane-worlds: I. Analytical results
Zoltán Keresztes, László Á. Gergely, Botond Nagy +1
The luminosity distance - redshift relation is analytically given for generalized Randall-Sundrum type II brane-world models containing dark radiation. The derived expressions cont…
An Efficient Method for the Evaluation of Secular Effects in the Perturbed Keplerian Motion
László Á. Gergely, Zoltán Keresztes, Balázs Mikóczi
Binary systems subject to generic perturbations evolve on quasiperiodic orbits. We derive the most generic class of perturbations, which allow to evaluate secular effects via gener…
The Kepler equation for inspiralling compact binaries
Zoltán Keresztes, Balázs Mikóczi, László Á. Gergely
Compact binaries consisting of neutron stars / black holes on eccentric orbit undergo a perturbed Keplerian motion. The perturbations are either of relativistic origin or are relat…
