Abstract

We present the first measurement of the planet frequency beyond the "snow line," for the planet-to-star mass-ratio interval −4.5 200) microlensing events during 2005–2008. The sampled host stars have a typical mass M host ∼ 0.5 M ☉ , and detection is sensitive to planets over a range of planet–star-...
