Gauge-invariant and coordinate-independent perturbations of stellar collapse. II: Matching to the exterior

Gauge-invariant and coordinate-independent perturbations of stellar collapse. II: Matching to the exterior
Gauge-invariant and coordinate-independent perturbations of stellar collapse. II: Matching to the exterior
In Paper I in this series we constructed evolution equations for the complete gauge-invariant linear perturbations of a time-dependent spherically symmetric perfect fluid spacetime. A key application of this formalism is the interior of a collapsing star. Here we derive boundary conditions at the surface of the star, matching the interior perturbations to the well-known perturbations of the vacuum Schwarzschild spacetime outside the star.

Abstract

In Paper I in this series we constructed evolution equations for the complete gauge-invariant linear perturbations of a time-dependent spherically symmetric perfect fluid spacetime. A key application of this formalism is the interior of a collapsing star. Here we derive boundary conditions at the surface of the star, matching the interior perturbations to the well-known perturbations of the vacuum Schwarzschild spacetime outside the star.
