Scientific paper

Galactic mass distributions produced by a fragmentation model (in addition to those published previously) are examined by allowing the cubical fragment to assume any orientation in space. All distributions examined closely resemble observed galactic luminosity profiles, and, among the variety produced, the special log I versus r(1/14) behavior of de Vaucouleurs' empirical law was found, as well as the exponential behavior of spirals. Because of the apparent success of the model, the initial conditions and analytical methods are reexamined in detail.
