Charged particle dynamics in magnetosphere generated by current loop around Schwarzschild black hole
Martin Kološ, David Kofroň
We present a theoretical study of the magnetic field generated by a toroidal current loop situated in the equatorial plane of a non-rotating Schwarzschild black hole, based on the…
Relativistic disks by Appell-ring convolutions
David Kofroň, Petr Kotlařík, Oldřich Semerák
We present a new method for generating the gravitational field of thin disks within the Weyl class of static and axially symmetric spacetimes. Such a gravitational field is describ…
Debye superpotential for charged rings or circular currents on Kerr black hole
David Kofroň, Petr Kotlařík
We provide an explicit, closed and compact expression for the Debye superpotential of a circular source. This superpotential is obtained by integrating the Green function of Teukol…
Cosmic strings in axisymmetric black hole spacetimes; the C--metric "engines"
David Kofroň
The interpretation of so-called cosmic string in black hole spacetimes has settled down to an unsatisfactory state. In this article we try to provide a different model for these co…
Separability of test fields equations on the C-metric background II. Rotating case and the Meissner effect
David Kofroň
We present the separation of the Teukolsky master equation for the test field of arbitrary spin on the background of the rotating C-metric. We also summarize and simplify some know…
Separability of test fields equations on the C-metric background
David Kofroň
In the Kerr-Newman spacetime the Teukolsky master equation, governing the fundamental test fields, is of great importance. We derive an analogous master equation for the non-rotati…
Variations on spacetimes with boost-rotation symmetry
Jiří Bičák, David Kofroň
Some new results on the boost-rotation symmetric spacetimes representing pairs of rotating charged objects accelerated in opposite directions are summarized. A particular attention…
