Description
The pasta phase in core-collapse supernova matter (finite temperatures and fixed pro-
ton fractions) is studied within relativistic mean field models. Three different calculations
are used for comparison, the Thomas-Fermi (TF), the Coexistence Phase (CP) and the
Compressible Liquid Drop (CLD) approximations. The effects of including light clusters in
nuclear matter and the densities at which the transitions between pasta configurations and
to uniform matter occur are also investigated. The free energy and pressure, in the space
of particle number densities and temperatures expected to cover the pasta region, are cal-
culated. Finally, a comparison with a finite temperature Skyrme-Hartree-Fock calculation
is drawn.
