We describe a class of exactly soluble semiclassical models for gravitational collapse obtained by patching dynamical spherically symmetric exterior space-times with cosmological interior space-times. These are generalizations of the Oppenheimer-Snyder type models to include classical and quantum scalar fields as sources for the interior metric, and null fluids with pressure as sources for the exterior metric. The polymer quantization method is used for the scalar field. The resulting semiclassical metrics exhibit novel features such as evaporating horizons and singularity avoidance.
