Both homogeneous and inhomogeneous matter (pasta phase) are described for neutral nuclear matter with fixed proton fractions and stellar matter subject to $\\beta$-equilibrium and trapped neutrinos. In homogeneous matter, $\\alpha$ particles are only present at densities below 0.02 fm$^{-3}$ and their presence decreases with the increase of the temperature and, for a fixed temperature, the $\\alpha$ particle fraction decrea","authors_text":"C.
