Disk-galaxy density distribution from orbital speeds using Newton's law, version 1.1
Abstract
Description
Given the dimensions(including thickness) of an axisymmetric galaxy, Newton's law is used in integral form to find the density distributions required to match a wide range of orbital speed profiles. Newton's law is not modified and no dark-matter halos are required. The speed distributions can have extreme shapes if they are reasonably smooth. Several examples are given.
10 pages,10 figures. Has better density accuracy near the galaxy center by moving the segment rod to the segment centroid, and reducing the allowable errors for the speed matches. Some small changes in text, table, figures
