The Dynamical Behaviour of our Planetary System
Proceedings of the Fourth Alexander von Humboldt Colloquium on Celestial Mechanics
Article
CoRoT is a space telescope which aims at studying internal structure of stars and detecting extrasolar planets. We present here a list of transits detected in the light curves of stars ob...

The CoRoT space observatory is a project which is led by the French space agency CNES and leading space research institutes in Austria, Brazil, Belgium, Germany and Spain and also the European Space Agency ESA...

After the discovery of more than 400 planets beyond our Solar System, the characterization of exoplanets as well as their host stars can be considered as one of the fastest growing fields in space science duri...

Chapter and Conference Paper
All results, achieved up to now, show the long term stability of our planetary system, although, especially the inner solar system is chaotic, due to some specific secular resonances. We study, by means of num...
Chapter and Conference Paper
The binary Gliese 86 is about 11 pc away from the Sun in the constellation Eridanus in the southern hemisphere; a Kl main sequence star (= m 1) and a brown dwarf (= m 2) build this dou...
Chapter and Conference Paper
In the General Sitnikov Problem two primaries of equal masses (m 1 = m 2) move on perturbed Keplerian orbits because of the presence of a third non-zero mass confined to the axis (z-axis) ...
Chapter and Conference Paper
Up to now ∼ 400 asteroids are known which move close to the Lagrangian equilibrium points L 4 (246) and L 5 (167) of Jupiter. In this investigation the orbits of all known Trojans ...
Chapter and Conference Paper
The orbits of 13 Trojan asteroids have been calculated numerically in the model of the outer solar system for a time interval of 100 million years. For these asteroids (1997) determined Lyapunov times less than 1...
Chapter
This chapter contains some new developments in the theory of dynamical systems.

Chapter
Since the last report, Commission 7 has supported IAU Symposium No. 172 “Dynamics, Ephemerides and Astrometry of the Solar System” (Paris, 1995) and co-supported IAU Colloquium No. 165 “Dynamics and Astrometry...
Article
We present the results of a numerical study on encounter frequencies of fictitious Halley-like comets with the planets in a dynamical model of the solar system, in which we take into account the gravitational ...
Chapter
The existence of gaps and groups in the distribution of outer belt asteroid orbits, at resonances with Jupiter’s orbit, is explained by different rates of destruction of the flow of regular motions by Saturn p...

Chapter and Conference Paper
We present numerical results of the so-called Sitnikov-problem, a special case of the three-dimensional elliptic restricted three-body problem. Here the two primaries have equal masses and the third body moves...

The Lyapunov characteristic numbers (LCNs) which are defined as the mean value of the distribution of the local variations of the tangent vectors to the flow (=ln α k i ...
Chapter and Conference Paper
We report on recent research of the elliptic restricted three-body-problem concerning the motion of Asteroids in the 2/1, 3/1 and 1/1 mean motion resonances with Jupiter. In a recent review (J. Henrard, 1988) ...
