A comparison of two spherical mass-distribution models

A comparison of two spherical mass-distribution models

Two spherically symmetric mass-distribution models - a special case of the generalized Schuster density law and the generalized isochrone model (both yield the same approximate density dependence on the distance in the outer parts) - are compared. It is shown that in the interval of the relative sec...
