Abstract (from CDS):

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 = 1.60± 0.02 AU and ac = 2.24 ± 0.05 AU, and have minimum masses (m sin i) of Mb = 1.96 ± 0.12 MJup and Mc = 1.76 ± 0.18 MJup. Detailed N-body dynamical simulations show that the two planets have remained on stable orbits for more than 106 years for low eccentricities and are most likely trapped in a mutual 3:5 mean motion resonance.
