Query: A new baryonic equation of state at sub-nuclear densities for
  core-collapse simulations   We calculate a new equation of state for baryons at sub-nuclear densities
meant for the use in core-collapse simulations of massive stars. The abundance
of various nuclei is obtained together with the thermodynamic quantities. The
formulation is the NSE description and the liquid drop approximation of nuclei.
The model free energy to minimize is calculated by relativistic mean field
theory for nucleons and the mass formula for nuclei with the atomic number up
to ~ 1000. We have also taken into account the pasta phase, thanks to which the
transition to uniform nuclear matter in our EOS occurs in the conventional
manner: nuclei are not dissociated to nucleons but survive right up to the
transition to uniform nuclear matter. We find that the free energy and other
thermodynamical quantities are not very different from those given in the
Shen's EOS, one of the standard EOS's that adopt the single nucleus
approximation. The average mass is systematically different, on the other hand,
which may have an important ramification to the rates of electron captures and
coherent neutrino scatterings on nuclei in supernova cores. It is also
interesting that the root mean square of the mass number is not very different
from the average mass number, since the former is important for the evaluation
of coherent scattering rates on nuclei but has been unavailable so far. The EOS
table is currently under construction, which will include the weak interaction
rates.
