摘要: Aims. We re-analyse the HARPS radial velocities of HD10180 and calculate probabilities models with differing numbers periodic signals in data. test significance seven signals, corresponding to exoplanets orbiting star, Bayesian framework perform comparisons up nine periodicities. Methods. used posterior samplings model our analyses together suitable prior probability densities extract all significant from data receive reliable uncertainties for orbital parameters six, possibly seven, known system. Results. According results, there is evidence planets HD10180, which would make this star a record holder more its orbits than are solar revise previously reported six system, verify existence seventh signal, announce detection two additional statistically
