# A Bayesian Periodogram Finds Evidence for Three Planets in 47 Ursae Majoris

@article{Gregory2010ABP, title={A Bayesian Periodogram Finds Evidence for Three Planets in 47 Ursae Majoris}, author={Philip C. Gregory and Debra A. Fischer}, journal={Monthly Notices of the Royal Astronomical Society}, year={2010}, volume={403}, pages={731-747} }

A Bayesian analysis of 47 Ursae Majoris (47 UMa) radial velocity data confirms and refines the properties of two previously reported planets with periods of 1079 and 2325 days. The analysis also provides orbital constraints on an additional long period planet with a period � 10000 days. The three planet model is found to be 10 5 times more probable than the next most probable model which is a two planet model. The nonlinear model fitting is accomplished with a new hybrid Markov chain Monte…
