Gravitational Energy in Spherical Symmetry
Sean A. Hayward
Various properties of the Misner-Sharp spherically symmetric gravitational energy E are established or reviewed. In the Newtonian limit of a perfect fluid, E yields the Newtonian m…
Spin-Coefficient Form of the New Laws of Black-Hole Dynamics
Sean A. Hayward
General laws of black-hole dynamics, some of which are analogous to the laws of thermodynamics, have recently been found for a general definition of black hole in terms of a future…
Quasi-Localisation of Bondi-Sachs Energy Loss
Sean A. Hayward
A formula is given for the variation of the Hawking energy along any one-parameter foliation of compact spatial 2-surfaces. A surface for which one null expansion is positive and t…
Confinement by Black Holes
Sean A. Hayward
The question of whether an observer can escape from a black hole is addressed, using a recent general definition of a black hole in the form of a future outer trapping horizon. An…
