Black hole, cosmic body of extremely intense gravity from which nothing, not even light, can escape. It can be formed by the death of a massive star wherein its core gravitationally collapses inward upon itself, compressing to a point of zero volume and

Finally, we make a comparison between the polarimetric images of Bonnor black dihole and M87*. Our result further confirms that the image of black hole depends on the black hole's properties itself, the matter around black hole and the corresponding radiation occurred in the accretion disk....
the central engines of the stellar mass accreting X-ray binary systems are thought to be primarily and generally from accretion disks (and coronae) and collimated jets, respectively, which provide an observational avenue to investigate the disk and jet correlation with the black hole mass [39]....
An example of such a flux eruption is depicted in Figure 1, and a more detailed description of the accretion flow’s response to these events is outlined in Appendix A. Figure 1. Magnetic flux eruptions can remove over half of the disk from near the black hole, significantly changing the ...
The Event Horizon Telescope’s global network of radio dishes has produced the first-ever direct image of a black hole and its event horizon.
Gravastars, hypothetic astrophysical objects, consisting of a dark energy condensate surrounded by a strongly correlated thin shell of anisotropic matter, have been proposed as an alternative to the standard black hole picture of general relativity. Observationally distinguishing between astrophysical black...
2) the importance of magnetic fields in many different respects, most importantly being responsible for the self-sustained MHD-turbulence giving rise to the disc viscosity, and 3) the details of the radiation processes giving rise to the X/gamma-ray continuum originating close to the black hole...
Thin accretion disk signatures of slowly rotating black holes in Hoava gravity In this work, we consider the possibility of observationally testing Hoava gravity by using the accretion disk properties around slowly rotating black hole... T Harko,Z Kovács,FSN Lobo - 《Classical & Quantum Gravity...
We construct stationary models of a slim accretion disk with including hydrogen burning. Energy generation through the CNO cycle is explicitly incorporated into the equations of structure. Viscous torque is prescribed in term of an 伪 parameter and mass accretion rate is set to be supercritical. ...
