Since the first extrasolar planet was discovered about 10 years ago, a
major point of dynamical investigations was the determination of stable
regions in extrasolar planetary systems where additional planets may
exist. Using numerical methods, we investigate the dynamical stability
in known multiple planetary systems (HD74156, HD38529, HD168443,
HD169830) with special interest on the region between the two known
planets and on the mean motion resonances inside this region. As a
dynamical model we take the restricted 4-body problem containing the
host star, the two planets and massless test-planets. For our numerical
integrations, we used the Lie-integrator and additionally the Fast
Lyapunov Indicators as a tool for detecting chaotic motion. We also
investigated the inner resonances with the outer planet and the outer
resonances with the inner planet with test-planets located inside the
resonances.
