Long Periods in the Three-Dimensional Motion of Trojan Asteroids

Abstract: The long periods caused by Jupiter, or Jupiter and Saturn in the motion of a Trojan are studied by numerical integration. Orbital inclinations between 0° and 50° are considered. Results on the length of the periods and on their main effects in the osculating elements are presented. It turns out that secular resonances can be important for the evolution of Trojan orbits.

Orbital Evolution of Trojan Asteroids

Abstract: The motion of the orbits of Trojan asteroids are investigated. Four asteroids around L5 are shown to have librating perihelion. A criterion for the libration of the perihelion is derived and expressed by the initial conditions. This criterion is solved for the initial conditions in two special cases. Thus regions in the configuration space of the initial conditions yielding libration of the orbits of Trojan asteroids are established.

A note on the normalized period of libration of Trojan asteroids

Abstract: A comparison is made between Garfinkel's and Erdi's theory of Trojan asteroids concerning the normalized period of libration nearL 4. An exact agreement is shown up to the fourth order of the parameter α0 of Garfinkel's solution.
