Searching for stable orbits in the HD10180 planetary system

Abstract. A planetary system with at least seven planets has been found around the star HD10180. However, the traditional Keplerian and n-body fits to the data provide an orbital solution that becomes unstable very quickly, which may quest the reliability of the observations. Here we show that stable orbital configurations can be obtained if general relativity and long-term dissipation raised by tides on the innermost planet are taken into account. 1
