Stability of the 47 UMa planetary system.
GOZDZIEWSKI K.
Abstract (from CDS):
In this paper we study the stability of the 47 UMa planetary system in the framework of the N-body problem, with application of the MEGNO technique. The method makes it possible to distinguish rapidly between chaotic and regular evolution of a planetary system. Using the initial conditions of the 47 UMa system found by Fischer et al. (2002ApJ...564.1028F) we estimate the dynamical bounds on orbital parameters that provide stable motions of the system. We analyze whether a telluric planet can survive orbitally in the habitable zone of the system.
