Landau excitation of spiral density waves in an inhomogeneous disk of stars Academic Article uri icon

abstract

  • Abstract Drift-resonant Landau excitation of spiral density waves in a stellar disk of flat galaxies is proposed. This excitation of waves is suggested as a mechanism for the formation of structural features such as spiral arms and the slow dynamical relaxation of galaxies in a regime of hydrodynamical Jeans-type stability.
