The pasta phases are calculated for warm stellar matter in a framework of
relativistic mean-field models, including the possibility of light cluster
formation. Results from three different semiclassical approaches are compared
with a quantum statistical calculation. Light clusters are considered as
point-like particles, and their abundances are determined from the minimization
of the free energy. The couplings of the light-clusters to mesons are
determined from experimental chemical equilibrium constants and many-body
quantum statistical calculations. The effect of these light clusters on the
chemical potentials is also discussed. It is shown that including heavy
clusters, light clusters are present until larger nucleonic densities, although
with smaller mass fractions.Comment: 15 pages, 13 figures, accepted for publication in Physical review
