Lectures given March 25 - 30, 1996, at the 26th SAAS-FEE Advanced Course:
GALAXIES: INTERACTIONS AND INDUCED STAR FORMATION.

  1. Theory of Interacting Galaxies
    leading actors - collisionless dynamics - parabolic encounters - TT models
  2. Numerical Stellar Dynamics
    Monte-Carlo simulation - force calculation - time integration - errors - relaxation effects
  3. Studies of Tidal Encounters
    galaxy models - encounter survey - the Antennae - the Mice - M51 - NGC 7252
  4. Gas Dynamics in Interacting Galaxies
    ISM dynamics - sticky & smooth particles - gas flows in perturbed disks - star formation & feedback
  5. Mechanics of Merging
    dynamical friction - orbit decay - violent relaxation - radial profiles - core radii - asymptotic structure
  6. Memory in Major Mergers
    fine structures - phase mixing - orbits in triaxial potentials - survival of disk kinematics
  7. Dissipation & Forgetting
    hydrodynamic encounters - thermodynamic evolution - timing of starbursts - counter-rotating components
  8. Accretions & Minor Mergers
    unequal-mass mergers - satellite accretions - shells & ripples - dissipative effects: rings
  9. Interactions in Groups & Clusters
    group dynamics - mergers in compact groups - fast encounters - cluster evolution
