Abstract

Five new planets orbiting G and K dwarfs have emerged from the Magellan velocity survey. These companions are Jovian-mass planets in eccentric (e ≥ 0.24) intermediate- and long-period orbits. HD 86226b orbits a solar metallicity G2 dwarf. The MP sin i mass of the planet is 1.5 M JUP, the semimajor axis is 2.6AU, and the eccentricity is 0.73. HD 129445b orbits a metal-rich G6 dwarf. The minimum mass of the planet is MP sin i = 1.6 M JUP, the semimajor axis is 2.9AU, and the eccentricity is 0.70. HD 164604b orbits a K2 dwarf. The MP sin i mass is 2.7 M JUP, the semimajor axis is 1.3AU, and the eccentricity is 0.24. HD 175167b orbits a metal-rich G5 star. The MP sin i mass is 7.8 M JUP, the semimajor axis is 2.4AU, and the eccentricity is 0.54. HD 152079b orbits a G6 dwarf. The MP sin i mass of the planet is 3 M JUP, the semimajor axis is 3.2AU, and the eccentricity is 0.60. © 2010 The American Astronomical Society.
