TL;DR
This paper introduces new simple models of black hole interiors that are physically valid, satisfy energy conditions, and are constructed as solutions matching Schwarzschild vacuum at certain hypersurfaces.
Contribution
The paper presents novel spherically symmetric black hole interior models with elastic matter content that meet energy conditions and match Schwarzschild vacuum solutions.
Findings
Models satisfy the weak energy condition
Matter content is specified by an elastic equation of state
Solutions match Schwarzschild vacuum at R<2M
Abstract
New, simple models of ``black hole interiors'', namely spherically symmetric solutions of the Einstein field equations in matter matching the Schwarzschild vacuum at spacelike hypersurfaces ``R<2M'' are constructed. The models satisfy the weak energy condition and their matter content is specified by an equation of state of the elastic type.
