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…
Schwarzschild binary supported by an Appell ring
O. Semerák, M. Basovník, P. Kotlařík
We continue to study black holes subjected to strong sources of gravity, again paying special attention to the behaviour of geometry in the black-hole interior. After examining, in…
Schwarzschild black hole encircled by a rotating thin disc: Properties of perturbative solution
P. Kotlařík, O. Semerák, P. Čížek
In ApJ (1974), Will solved the perturbation of a Schwarzschild black hole due to a slowly rotating light concentric thin ring, using Green's functions expressed as infinite-sum exp…
