Web18.1 Material Arms & Density Waves. Because disk galaxies rotate differentially, the orbital period is an increasing function of radius R.Thus if spiral arms were material features then differential rotation would would soon wind them up into very tightly-coiled spirals. The expected pitch angle of material arms in a spiral galaxy like the Milky Way is only about … WebOnce formed, N-body bars are found to be long-lived, dominate the disc dynamics and are responsible for driving secular evolution processes in the galaxy (Sellwood & Wilkinson 1993). Fig. 2 depicts the formation and evolution of the bar from the initially axisymmetric disc. Strong two-armed spirals are also formed along with the bar and last ...
