Abstract

A model is proposed to describe a transition from a Schwarzschild black hole of mass M₀ to a Schwarzschild black hole of mass M₁ ≤ M₀. The basic equations are derived from the non-vacuum Einstein field equations taking a source representing a null scalar field with a nonvanishing trace anomaly. It is shown that the nonvanishing trace anomaly of the scalar field prevents a complete evaporation.
