Initial evolutionary stages for the halo of the constructed disk galaxy model (with triaxial halo and star-forming gas). We show the dependence of various quantities on the spherical radius r for various moments of time, a) shows radial profiles of axial ratios b/a and c/a. These profiles were calculated by means of the method described in Machado & Athanassoula (2010); b) shows the profile of the number of particles n in concentric spherical layers; c) shows the profile of the radial velocity dispersion.
