Query: The Pan-Pacific Planet Search. I. A Giant Planet Orbiting 7 CMa   We introduce the Pan-Pacific Planet Search, a survey of 170 metal-rich
Southern hemisphere subgiants using the 3.9m Anglo-Australian Telescope. We
report the first discovery from this program, a giant planet orbiting 7 CMa (HD
47205) with a period of 763+/-17 days, eccentricity e=0.14+/-0.06, and m sin
i=2.6+/-0.6 M_jup. The host star is a K giant with a mass of 1.5+/-0.3 M_sun
and metallicity [Fe/H]=0.21+/-0.10. The mass and period of 7 CMa b are typical
of planets which have been found to orbit intermediate-mass stars (M*>1.3
M_sun). Hipparcos photometry shows this star to be stable to 0.0004 mag on the
radial-velocity period, giving confidence that this signal can be attributed to
reflex motion caused by an orbiting planet.
