Teukolsky Master Equation for a Kerr-like metric with Mass Quadrupole Moment

Pedro Gómez, Adrián Eduarte-Rojas, Francisco Frutos-Alfaro +1

The Teukolsky Master Equation (TME) is a powerful technique used to study perturbations of a spacetime with gravitational, electromagnetic, and neutrino components. The well-known…

Chaotic Dynamics due Prolate and Oblate Sources in Kerr-like and Hartle-Thorne Spacetimes with and without Magnetic Field

Adrián Eduarte-Rojas, Francisco Frutos-Alfaro, Rodrigo Carboni

As demonstrated by observations, every stellar-mass object rotates around some axis; some objects spin faster than others due to different mechanisms. Furthermore, these spinning o…

Innermost Stable Circular Orbits of a Kerr-like Metric with Quadrupole

Fabián Chaverri-Miranda, Francisco Frutos-Alfaro, Diego Solano-Alfaro +2

This paper presents results for the innermost stable circular orbit in a Kerr-like spacetime. The metric employed is an approximation that combines the Kerr metric with the Erez-Ro…

Transparent Spheres as Gravitational Lens

Edwin Santiago-Leandro, Alexander Mora-Chaverri, Francisco Frutos-Alfaro

In this contribution, we present a short account of gravitational lenses and how to calculate different properties of its images in the case of having a transparent distribution of…

Classical general relativity effects by magnetars with massive quadrupole, angular momentum and a magnetic dipole

Alexander Mora-Chaverri, Edwin Santiago-Leandro, Francisco Frutos-Alfaro

In this contribution, we obtain classical tests of general relativity using the Hartle-Thorne metric endowed with magnetic dipole and electric charge. This metric represents the ap…

Equatorial circular motion in a Kerr-like spacetime

Diego Solano-Alfaro, Francisco Frutos-Alfaro

An study of the equatorial circular motion of photons and massive particles around a rotating compact body like a neutron star is presented. For this goal, we use an approximate Ke…
