  A detailed description is given of the phase diagram for a two-component
unitary Fermi gas with mass and population imbalance, for both homogeneous and
trapped systems. This aims at providing quantitative benchmarks for the
normal-to-superfluid phase transition of a mass-imbalanced Fermi gas in the
temperature-polarization parameter space. A self-consistent t-matrix approach
is adopted, which has already proven to accurately describe the thermodynamic
properties of the mass and population balanced unitary Fermi gas. Our results
provide a guideline for the ongoing experiments on heteronuclear Fermi
mixtures.
