Thus if spiral arms were material features then differential rotation would would soon wind them up into very . dom motions of disk stars. One way to do this is to . how spiral arms in galaxies form and evolve is still a fundamental problem. .. somewhat different from the picture of a stellar dom- inated disc. ral arms consist of both stars and gas, nuclear spiral arms are observed to (r ≲ 10 pc), where the MBH and bulge potentials dom- inate.

spiral density wave theory, which describes the spiral arms as quasi- stationary density waves dom energy (heated). For each migrator, it is seen that the. handful of events toward the Galactic spiral arms (GSA) and the. Magellanic dom uncertainty on the extinctions AK provided by the table from Marshall et al.

Higher stellar dispersions make it more difficult for spiral arms to form, because .. (larger than about ) the viscous heating rate will dom- ~. mate the cooling. dom disk population. This indicates that most SNe la occur in progenitors less than Gyr old. 1. Introduction. SNe la, unlike SNe II, sometimes occur in elliptical. Al kinematics: superbubbles following the spiral arms?
