摘要：

Comparative analysis of the parent stars of extrasolar planetary systems and the local disk population shows a strong trend for increasing frequency with increasing abundance. Approximately 4.5% of solar-abundance (-0.15 < [m/H] less than or equal to +0.15) stars have detectable planetary-mass companions.
