Microlens OGLE-2005-BLG-169 Implies That Cool Neptune-like Planets Are Common
We detect a Neptune mass ratio (q ≃ 8 × 10-5) planetary companion to the lens star in the extremely high magnification (A ~ 800) microlensing event OGLE-2005-BLG-169. If the parent is a main-sequence star, it has mass M ~ 0.5 M☉, implying a planet mass of ~13 M⊕ and …
