Inhomogeneous Stellar Models. III. Models with Partially Degenerate Isothermal Cores.

A search was made for conditions under which models with partially degenerate isothermal cores could give radii as large as those of red giants. Special conditions were found for which detailed computations gave, indeed, models fitting well the red giants in radius and luminosity. But it has not been investigated whether the special conditions are likely to be realized in the evolution of a star.
