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.
