Dynamical Property of the OGLE-2006-BLG-109L Planetary System

摘要：

OGLE-06-109L is the first multiple system observed by gravitational mi crolensing. It is thought as the analogy of the our solar system. Due to the uncertainty of the orbital elements, the aim of the paper is twofold: (1) to determine the config uration of the two planets, (2) to locate the stable region inside their orbits. We find it is very unlikely that OGLE-06-109L b and c is in 3:1 resonance (with a probability ～ 1％), and the habitable zone of the system is stable.
