Three-Dimensional Galaxies, Flat Rotation Curve, Mass Density Distribution

Scientific paper

Based on the method of Paper I and concentrating on the rigidly rotating, inner region of the galaxy, a theoretical investigation is carried out here on the asymptotic property of the projected surface density σ(r) combining with the asymptotic solution of Paper I for the outer region with flat rotation curve, I suggest the form σ(r) = σ0(1 - 4/5br+r2/a2)-5/4exp(-br) as a possible, reasonable mass model for the whole galactic disk. In the course of the study, an important relation between the masses of the bulge and the disk and certain parameters characterizing the distribution was found.
