    Title: ON THE DENSITY-WAVE THEORY OF GALACTIC SPIRALS .2. PROPAGATION OF DENSITY OF WAVE ACTION
    Authors: SHU, F.H.
    教師: 徐遐生
    Date: 1970
    Publisher: American Astronomical Society
    Relation: ASTROPHYSICAL JOURNAL, American Astronomical Society, Volume 160, Issue 1, 1970, Pages 99-112
    Keywords: DENSITY-WAVE THEORY
    PROPAGATION
    Abstract: The properties of galactic density waves are studied in the WKBJ approximation. In the lowest order of approximation, we reproduce the dispersion relation reported by Lin and Shu in an earlier communication. In the next order, we demonstrate explicitly that the density of “wave action” is transported with the group velocity derived by Toomre. Some general implications are drawn for mechanisms proposed for the origin of spiral structure.
