... We now know that at the center of this wheel is an enormous black hole--a collapsed star with mass 3-4 million times that of the Sun, and gravity so strong that even light cannot escape. ...
... X-ray binaries harbor stellar mass black holes - endpoints of the evolution of massivestars. ... and (possibly) intermediate mass black holes in X-ray binaries and ultra-luminous X-ray sources in star-forming galaxies can ...
... I will review the dynamical role of magnetic fields in extracting the energy of a relativistic rotating progenitor (like black hole ili super-massive neutron star), in collimating the outflow and in producing the observed high energy emission. ...
... Low-massstars crush their atoms and become white dwarfs , about as big as Earth. ... High massstars collapse into black holes whose gravity prevents any light from ...
