The vast majority of known extrasolar planets orbit stars with a narrow rangeof masses (0.7-1.3 M_sun). Recent years have seen rapid growth in our knowledgeabout the properties of planetary systems with host stars significantly moremassive than the Sun. Planet formation models predict that giant planets aremore common around higher-mass stars (M>1.5M_sun). However, these types ofstars pose severe observational challenges while on the main sequence,resulting in a strong bias against them in current planet searches.Fortunately, it is possible to obtain high-precision Doppler velocities forthese massive stars as they evolve off the main sequence and cool as subgiants.We describe the Pan-Pacific Planet Search, a survey of 170 subgiant stars usingthe 3.9m Australian Astronomical Telescope. In collaboration with J. Johnson'sKeck survey of Northern retired A stars, we are monitoring nearly everysubgiant brighter than V=8. This survey will provide critical statistics on thefrequency and characteristics of planetary systems formed around higher-massstars.
