  In this work, we investigate how the assumption of chemical equilibrium with
leptons affects the deconfinement phase transition to quark matter. This is
done within the framework of the Chiral Mean Field model (CMF) allowing for
non-zero net strangeness, corresponding to the conditions found in
astrophysical scenarios. We build 3-dimensional QCD phase diagrams with
temperature, baryon chemical potential, and either charge or isospin fraction
or chemical potential to show how the deconfinement region collapses to a line
in the special case of chemical equilibrium, such as the one established the
interior of cold catalyzed neutron stars.
