AbstractAbstract We report the discovery of a super-Jovian planet in the microlensing event KMT-2016-BLG-1836, which was found by the Korea Microlensing Telescope Network (KMTNet) high-cadence observations ( ). The planet–host mass ratio q?~?0.004. A Bayesian analysis indicates that the planetary system is composed of a super-Jovian planet orbiting an M or K dwarf, , at a distance of kpc. The projected planet–host separation is au, implying that the planet is located beyond the snow line of the host star. Future high-resolution images can potentially strongly constrain the lens brightness and thus the mass and distance of the planetary system. Without considering detailed detection efficiency, selection, or publication biases, we find a potential mass-ratio desert at??3.7???log?q????3.0 for the 31 published KMTNet planets.
