Flat rotational curves without dark matter
arXiv:astro-ph/0611303
Abstract
We consider the singular configurations of gravitating gas [1] which could be used as a model for disk galaxies. The simplest steady configuration, which corresponds to rotation of stars around center gives flat rotational curve, provided the density distrubution has a tail, decaying as 1/r. This result based exclusively on Newtonian gravity and does not involve dark matter.
