Scientific paper

We study the conditions that favour boxiness of isodensities in the face-on views of orbital 3D models for barred galaxies. In particular, we consider several cases with different mass values for the bar, disk and bulge components of the potential, as well as different values of the bar pattern speed. Using orbital weighted profiles of the basic stable periodic orbits of the x1 tree for every model, we show that boxiness is in general a composite effect due to the presence of stable orbits belonging to several 2D and 3D families.
