How Unusual are Stars with Planets?
Published online by Cambridge University Press: 19 September 2017
Abstract
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] ≤ +0.15) stars have detectable planetary-mass companions.
