OGLE-2015-BLG-1609Lb: a sub-Jovian planet orbiting a low-mass stellar or brown dwarf host

We present a comprehensive analysis of the planetary microlensing event OGLE-2015-BLG-1609. The planetary anomaly was detected by two survey telescopes, OGLE and MOA. Both surveys collected enough data over the planetary anomaly to enable an unambiguous planet detection. Such survey detections of pl...
