Query: Model--space approach to $^{1}S_{0}$ neutron and proton pairing with the
  Bonn meson--exchange potentials   In this work we calculate neutron and proton energy gaps in neutron star
matter, using the Bonn meson--exchange interactions and a model--space approach
to the gap equation. This approach allows a consistent calculation of energy
gaps and single particle energies with the model--space
Brueckner--Hartree--Fock (MBHF) method, without double counting of
two--particle correlations. Neutron energy gaps are calculated at zero and
finite temperature. Proton energy gaps are calculated at beta equilibrium, and
it is shown that the inclusion of muons has a significant effect. The results
are compared with those of other works, and the implications for neutron star
physics are briefly discussed.
