Abstract (from CDS):

We report the detection of the first two planets from the N2K Doppler planet search program at the Magellan telescopes. The first planet has a mass of Msin i = 4.96 MJup and orbits the G3 IV star HD 154672 with an orbital period of 163.9 days. The second planet orbits the F7 V star HD 205739 with an orbital period of 279.8 days and has a mass of Msin i = 1.37 MJup. Both planets are in eccentric orbits, with eccentricities e = 0.61 and e = 0.27, respectively. Both stars are metal rich and appear to be chromospherically inactive, based on inspection of their Ca II H and K lines. Finally, the best Keplerian model fit to HD 205739b shows a trend of 0.0649 m s–1 day–1, suggesting the presence of an additional outer body in that system.
