摘要: This paper is an updated version of lectures given at the Helmholtz Summer School on Extrasolar Planetary Systems (Potsdam, 2003). It includes five sections: Orbit determination, known planetary systems, chaos, transition from secular to resonant dynamics and migration. The first section mainly devoted problems arising in orbit determination systems with 2 or more planets data radial velocity central star. In second section, attempt classification done which are grouped 4 classes, one 47 UMa our Solar System (orbits low period ratio small eccentricities). phenomena related mean-motion resonances (MMR) studied some detail remaining sections, since they may directly affect stability many systems. appendix, FFT techniques used assess a system reviewed.
