An analysis of a regular black hole interior model
  We analyze the thermodynamical properties of the regular static and
spherically symmetric black hole interior model presented by Mboyne and
Kazanas. Equations for the thermodynamical quantities valid for an arbitrary
density profile are deduced, and from them we show that the model is
thermodynamically unstable. Evidence is also presented pointing to its
dynamical instability. The gravitational entropy of this solution based on the
Weyl curvature conjecture is calculated, following the recipe given by Rudjord,
Gr$\varnothing$n and Sigbj$\varnothing$rn, and it is shown to have the expected
behavior.
