On the Distribution of Mass in Galaxies. III. Surface Densities.
Abstract
The theory for the analysis of galactic rotation-curves using a sequence of spheroidal homoeoids compressed into a disk is extended to yield surface densities. The results are compared with existing determinations of surface densities from rotation curves for M31 and NGC 5055.
