TL;DR
This paper develops a new model of relativistic stars by extending the Vaidya metric to include both radiation and string fluids, resulting in novel analytic solutions to Einstein's equations.
Contribution
It introduces an extended Vaidya metric incorporating string fluids and derives new analytic solutions assuming diffusive transport.
Findings
Extended Vaidya metric with radiation and string fluids
New analytic solutions to Einstein's equations
Modeling of relativistic stars with combined fluids
Abstract
We have extended the Vaidya radiating metric to include both a radiation fluid and a string fluid. This paper expands our brief introduction to extensions of the Schwarzschild vacuum which appeared in 1998 Phys. Rev. D Vol 57, R5945. Assuming diffusive transport for the string fluid, we find new analytic solutions of Einstein's field equations.
