Resonant trapping in the galactic disc and halo and its relation with moving groups
Monthly Notices of the Royal Astronomical Society(2015)
摘要
With the use of a detailed Milky Way non-axisymmetric potential, observationally and dynamically constrained, the effects of the bar and the spiral arms in the Galaxy are studied in the disc and in the stellar halo. Especially the trapping of stars in the disc and Galactic halo by resonances on the Galactic plane, induced by the Galactic bar, has been analysed in detail. To this purpose, a new met...
