Scientific paper

A simple heuristic model for warping in the arms of spiral galaxies is presented to describe the structures of barred galaxies. A simulation for a microcomputer was developed by approximating the basic large-scale features of a normal spiral galaxy in Cartesian coordinates. Warping was introduced along the z-axis and the projection was rotated to detect changes with the orientation of viewing. The warping patterns selected were within the constraints of observational data on spiral galaxies, and bar structures were found that corresponded with those seen, e.g., with NGC 1300, NGC 2523, NGC 1398, and NGC 4394.
