Modeling the Milky Way disk dynamics

IntroductionVelocities of stars in the solarneighbourhood (~150 pc)GCS (Hipparcos + Geneva-Copenhagen)• Disrupted stellar clusterse.g. HR1614 (Feltzing and Holmberg 2000, DeSilva et al. 2007)•Tidal debris of accreted satellitese.g. Arcturus ? (Navarro et al. 2004)•Perturbations in the disc due toexternal dynamical effects (e.g. due tointeraction events)Quillen et al. 2009, Minchev et al. 2009•Orbital and resonant effects of thespiral arms and barKalnajs 1991, Dehnen 2000, Fux 2000, Quillen &Minchev 2005, Chakrabarty 2007, Antoja et al.2009T.
