Boson Stars surrounded by Polish Doughnuts in Scalar-Tensor Theory
Kristian Gjorgjieski, Maxim Rose, Burkhard Kleihaus +2
We investigate thick accretion disks (Polish Doughnuts) around rotating self-interacting boson stars in general relativity and scalar-tensor theories, focusing on spontaneously sca…
Matter Accumulations and Accretion Tori around Wormholes
Kristian Gjorgjieski, Jutta Kunz, Petya Nedkova
We study circular orbits and accretion structures around symmetric wormholes. As exemplary solutions we choose three different wormhole spacetimes, namely rotating traversable worm…
Circular Orbits and Photon Orbits at Wormhole Throats
Kristian Gjorgjieski, Jutta Kunz, Petya Nedkova
In this work we study timelike circular orbits and photon orbits at the throat of stationary and axisymmetric wormholes. Our minimal requirements on the spacetime are the existence…
Accretion Structures around Kerr Black Holes in a Swirling Background
Kristian Gjorgjieski, Rogério Capobianco
We investigate thick accretion structures around Kerr black holes in a swirling background. This stationary and axisymmetric spacetime is composed of a rotating black hole, which i…
Comparison of Magnetized Thick Disks around Black Holes and Boson Stars
Kristian Gjorgjieski, Jutta Kunz, Petya Nedkova
Boson stars are considered as promising candidates for black hole mimickers. Similar to other compact objects they can form accretion disks around them. The properties of these dis…
Magnetized Thick Disks around Boson Stars
Kristian Gjorgjieski, Jutta Kunz, Matheus C. Teodoro +2
The effects of magnetic fields on accretion disks around compact objects are of high importance in the study of their general properties and dynamics. Here we analyze the influence…
