Some of them can have up to 29% of their energy extracted by processes operating inside the static limit. One such process, superradiant scattering, operates in a frequency regime given by the area theorem. They emit blackbody radiation with a temperature equal to the surface gravity over two pi, in a process involving pair production.  They form above the Oppenheimer-Volkoff limit, the highest possible mass for a neutron star.  The Penrose process and Hawking radiation are both associated with, FTP, what class of compact objects so massive that even light cannot escape from within their event horizons?
