Formation and transformation of the 3:1 mean-motion resonance in 55 Cancri System
Li-Yong Zhou, Sylvio Ferraz-Mello, Yi-Sui Sun
We report in this paper the numerical simulations of the capture into the 3:1 mean-motion resonance between the planet b and c in the 55 Cancri system. The results show that this r…
Do N-planet systems have a boundary between chaotic and regular motions?
Ji-Lin Zhou, Yi-Sui Sun
Planetary systems consisting of one star and n planets with equal planet masses μand scaled orbital separation are referred as EMS systems. They represent an ideal model for planet…
Post-Oligarchic Evolution of Protoplanetary Embryos and the Stability of Planetary Systems
Ji-Lin Zhou, Douglas N. C. Lin, Yi-Sui Sun
We investigate the orbit-crossing time (T_c) of protoplanet systems both with and without a gas-disk background. The protoplanets are initially with equal masses and separation (EM…
The apsidal corotation in mean motion resonance: the 55 Cancri as an example
Li-Yong Zhou, Harry J. Lehto, Yi-Sui Sun +1
The inner two planets around the 55 Cancri were found to be trapped in the 3:1 mean motion resonance. In this paper, we study the dynamics of this extra-solar planetary system. Our…
Occurrence and Stability of Apsidal Resonance in Multiple Planetary Systems
Ji-Lin Zhou, Yi-Sui Sun
With the help of the Laplace-Lagrange solution of the secular perturbation theory in a double-planet system, we study the occurrence and the stability of apsidal secular resonance…
