Abstract
The stability of hypothetical Trojan planets in exoplanetary systems is investigated. In the model of the planar three-body problem, corresponding to a gravitational system of a star, a giant planet and a Trojan planet, the stability regions for the Trojan planet around the Lagrangian point L4 are determined depending on the mass of the two planets and the initial eccentricity of the orbit of the giant planet. The results indicate that in exoplanetary systems with one giant planet of several Jupiter-masses, a Trojan planet up to one Jupiter-mass can exist in stable motion around L4.
