Abstract (from CDS):

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 (Γ∼4hr–1). The planet-host mass ratio q ∼ 0.004. A Bayesian analysis indicates that the planetary system is composed of a super-Jovian Mplanet=2.2–1.1+1.9MJ planet orbiting an M or K dwarf, Mhost=0.49–0.25+0.38M☉, at a distance of DL=7.1–2.4+0.8 kpc. The projected planet-host separation is 3.5–0.9+1.1 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.
