“Dynamical Chaos near Corotation: Limits on cold radial migration”

 

Abstract:

 

After an initial epoch of assembly, spiral galaxies like the Milky Way evolve primarily under the influence of slow, internal processes.  This secular evolution rearranges the orbital angular momentum and energy of the disk, thus altering its kinematics, morphology and chemical distribution.  Dynamical resonances with spiral arms cause stars to migrate large radial distances from their birth radii....
