Inman, C.I., 1965: Baryon star models. Astrophys. J., 141, 187-194, doi:10.1086/148101.
We consider, in the framework of general relativity, large masses consisting of identical baryons (whose mass is taken to be that of the neutron). Four assumptions are made as to their interactions, leading to four equations of states, and for each the masses and radii of a number of configurations are calculated for various values of the central number density. The relations of the mass to a parameter t0 (= 4 sinh-1 [ℏ/mBc(3π2n0)1/3], where n0 is the central number density) for each of the four equations of state are strikingly similar.
