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…
Polarized Equatorial Emission around Kerr Black Holes with Synchronized Scalar Hair. I. Direct images
Valentin O. Deliyski, Galin N. Gyulchev, Daniela D. Doneva +2
We investigate the polarization properties of the direct images of a geometrically and optically thin accretion disk around fully self-consistent models of rotating Kerr black hole…
Images of the Thin Accretion Disk Around Kerr Black Holes coupled to time periodic scalar fields
Galin N. Gyulchev, Daniela D. Doneva, Valentin O. Deliyski +2
We investigate the orbital structure and observable appearance of rotating Kerr black holes endowed with synchronized scalar hair described by two time-periodic scalar fields with…
