Inertia tensor and tidal transfer of angular momentum for special ellipsoidal mass distributions

This paper deals with ellipsoidal mass distributions made by concentric, coaxial, and similar shells, whose density is specified for two special situations both including the whole range between the limiting cases of homogeneous systems, on one side, and Roche generalized systems, on the other side. The components of the related inertia tensor are calculated and the dependence of the spin growth on the density distribution is shown, concerning tidal transfer of angular momentum to both virialized proto-galaxies and encountering galaxies.
