AbstractAn expression for galactic density has been derived from galactic rotation curves using Burbidge technique, in which rotational velocity v(r) is related to the galactic density at a given distance r. Abel's integral has been used to evaluate the galactic density (r, k). The derived density law has been applied to spiral galaxies with a general observed rotation curves with a turn-over at some distance rt, so we got two different density forms 1(r, k) and 2(r, k) for the core and for disk and halo of the galaxy respectively.
