Abstract (from CDS):

We present high-precision radial-velocity measurements of three solar-type stars: HD13908, HD159243, and HIP91258. The observations were made with the SOPHIE spectrograph at the 1.93 m telescope of the Observatoire de Haute-Provence (France). They show that these three bright stars host exoplanetary systems composed of at least two companions. HD13908,HD159243 is a planet with a minimum mass of 0.865±0.035MJup on a circular orbit with a period of 19.382±0.006-days. There is an outer massive companion in the system with a period of 931±17-days, e=0.12±0.02, and a minimum mass of 5.13±0.25MJup. The star HD159243, also has two detected companions with respective masses, periods, and eccentricities of Mp=1.13±0.05 and 1.9±0.13MJup, P=12.620±0.004 and 248.4±4.9-days, and e=0.02±0.02 and 0.075±0.05. Finally, the star HIP91258 has a planetary companion with a minimum mass of 1.068±0.038MJup, an orbital period of 5.0505±0.0015-days, and a quadratic trend indicating an outer planetary or stellar companion that is as yet uncharacterized. The planet-hosting stars HD13908, HD159243, and HIP91258 are main-sequence stars of spectral types F8V, G0V, and G5V, respectively, with moderate activity levels. HIP91258 is slightly over-metallic, while the other two stars have solar-like metallicity. The three systems are discussed in the frame of formation and dynamical evolution models of systems composed of several giant planets.
