Stable chaos in the 55Cnc exoplanetary system?
GAYON J., MARZARI F. and SCHOLL H.
Abstract (from CDS):
The five planets discovered around the main-sequence star 55Cnc may represent a case of stable chaos. By using both the Frequency Map Analysis and MEGNO, we find that about 15 per cent of the systems that can be build from the nominal orbital elements of the system are highly chaotic. However, in spite of the fast diffusion rate in the phase space, the planetary system is not destabilized over 400 Myr and close encounters between the planets are avoided.
