Energy Extraction From Gravitational Collapse to Static Black Holes
Remo Ruffini, Luca Vitagliano
The mass--energy formula of black holes implies that up to 50% of the energy can be extracted from a static black hole. Such a result is reexamined using the recently established a…

Irreducible mass and energetics of an electromagnetic black hole
Remo Ruffini, Luca Vitagliano
The mass-energy formula for a black hole endowed with electromagnetic structure (EMBH) is clarified for the nonrotating case. The irreducible mass is found to be…

On the electromagnetic field of a charged collapsing spherical shell in general relativity
Christian Cherubini, Remo Ruffini, Luca Vitagliano
A new exact solution of the Einstein-Maxwell equations for the gravitational collapse of a shell of matter in an already formed black hole is given. Both the shell and the black ho…
