Three-dimensional general relativistic Poynting-Robertson effect. III. Static and non-spherical quadrupolar massive source
Vittorio De Falco, Pavel Bakala, Maurizio Falanga
We investigate the three-dimensional motion of a test particle in the gravitational field generated by a non-spherical compact object endowed with a mass quadrupole moment, describ…
Three-dimensional general relativistic Poynting-Robertson effect II: Radiation field from a rigidly rotating spherical source
Pavel Bakala, Vittorio De Falco, Emmanuele Battista +4
We investigate the three-dimensional, general relativistic Poynting-Robertson effect in the case of rigidly rotating spherical source which emits radiation radially in the local co…
A new approximation of photon geodesics in Schwarzschild spacetime
Riccardo La Placa, Pavel Bakala, Luigi Stella +1
In this research note we introduce a new approximation of photon geodesics in Schwarzschild spacetime which is especially useful to describe highly bent trajectories, for which the…
The three-dimensional general relativistic Poynting-Robertson effect I: radial radiation field
Vittorio De Falco, Pavel Bakala, Emmanuele Battista +3
In this paper we investigate the three-dimensional (3D) motion of a test particle in a stationary, axially symmetric spacetime around a central compact object, under the influence…
Life under a black sun
Tomáš Opatrný, Lukáš Richterek, Pavel Bakala
Life is dependent on the income of energy with low entropy and the disposal of energy with high entropy. On Earth, the low-entropy energy is provided by solar radiation and the hig…
A virtual trip to the Schwarzschild-de Sitter black hole
P. Bakala, P. Cermak, S. Hledik +2
We developed realistic fully general relativistic computer code for simulation of optical projection in a strong, spherically symmetric gravitational field. Standard theoretical an…
