Abstract

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 {a}_b\=1.60+/- 0.02 AU and {a}_c=2.24+/- 0.05 AU, and have minimum masses (m sin I) of {M}_b=1.96+/- 0.12 {M}_{{Jup}} and {M}_c=1.76+/- 0.18 {M}_{{Jup}}. 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.
