review text: In order to study the structure of a chemically homogeneous star in equilibrium, a density profile of the form \(\rho \sim T^ N\exp(-\mu m(\Phi -\Phi_*)/kT)\) is suggested. As for polytropes, qualitative aspects of the resulting stellar model can be discussed analytically. In particular it is shown that one reobtains for \(N=3\) Eddington's standard model, whereas for \(N<3\) nearly polytropic models result.
