Gravitational collapse in cubic Horndeski theories
(IOP Publishing Ltd, 2020-11-19)We study spherically symmetric gravitational collapse in cubic Horndeski theories of gravity. By varying the coupling constants and the initial amplitude of the scalar field, we determine the region in the space of couplings ... -
Hamilton-Jacobi hydrodynamics of pulsating relativistic stars
(IOP Publishing, 2020-08-06)The dynamics of self-gravitating fluid bodies is described by the Euler–Einstein system of partial differential equations. The break-down of well-posedness on the fluid–vacuum interface remains a challenging open problem, ...
