A pair of Jovians in a 3:5 resonance at HD 33844

The Pan-Pacific Planet Search. IV. Two super-Jupiters in a 3:5 resonance orbiting the giant star HD33844
http://arxiv.org/abs/1512.07316

We report the discovery of two giant planets orbiting the K giant HD 33844 based on radial velocity data from three independent campaigns. The planets move on nearly circular orbits with semimajor axes ab=1.600.02 AU and ac=2.240.05 AU, and have minimum masses (m sin i) of Mb=1.960.12 Mjup and Mc=1.760.18 Mjup. Detailed N-body dynamical simulations show that the two planets remain on stable orbits for more than 106 years for low eccentricities, and are most likely trapped in a mutual 3:5 mean-motion resonance.
