The formation of bars in barred spiral galaxies is primarily thought to occur via slow evolution. This process involves the gradual rearrangement of stars and gas in the galaxy due to gravitational interactions and dynamical instabilities. Over time, these factors can lead to the formation of a bar structure across the galaxy.
