Gravitational energy in spherical symmetry

Abstract: 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 mass to leading order and the Newtonian kinetic and potential energy to the next order. For test particles, the corresponding Hájíček energy is conserved and

“…It would be preferable to have independently motivated definitions of these quantities, but so far this has been done only in spherical symmetry [19,20,21], where there are natural definitions of E, κ and Φ = Q/R which can be applied anywhere in the space-time, coinciding with the above expressions on the outer horizons of a ReissnerNordström black hole. In the dynamical context, E ≥ M is generally not the ADM energy, since there may be matter or gravitational radiation outside the black hole.…”

“…So a black hole grows if something falls into it, otherwise staying the same size. Comprehensive treatments were subsequently given for spherical symmetry [19,20,21], cylindrical symmetry [22] and a quasi-spherical approximation [23,24,25,26]. In each case, definitions were found for all the non-zero physical quantities mentioned above, providing prototypes of all except J and Ω.…”

“…In this paper, we adopt the "trapping horizon" framework introduced by Hayward [7,8] because this provides a systematic and mathematically transparent view of the sort of cosmological black holes treated here. In the context of this paper, trapping horizons and conventional apparent horizons are almost equivalent but they need not be in more general situations.…”
