Quasilocal mass and multipole expansion in scalar-tensor gravity
arXiv:1907.08055 · doi:10.1103/PhysRevD.100.084015
Abstract
A generalization of the Hawking-Hayward quasilocal mass to scalar-tensor gravity is compared, in vacuo and for asymptotically flat stationary geometries, with a recent multipole expansion of the gravitational field. The quasilocal mass seen at spatial infinity coincides with the monopole term, lending credibility to this construct.
