OGLE-2019-BLG-0362Lb: A Super-Jovian-Mass Planet around a Low-Mass Star

Uproszczony widok
dc.abstract.enWe present the analysis of a planetary microlensing event OGLE-2019-BLG-0362 with a short-duration anomaly (~0.4 days) near the peak of the light curve, which is caused by the resonant caustic. The event has a severe degeneracy with Δχ^{2} = 0.9 between the close and the wide binary lens models both with planet-host mass ratio q ≃ 0.007. We measure the angular Einstein radius but not the microlens parallax, and thus we perform a Bayesian analysis to estimate the physical parameters of the lens. We find that the OGLE-2019-BLG-0362L system is a super-Jovian-mass planet M_{p}=3.26^{+0.83}_{-0.58} M_{J} orbiting an M dwarf M_{h} = 0.42^{+0.34}_{-0.23} M_{⊙} at a distance D_{L} = 5.83^{+1.04}_{-1.55} kpc. The projected star-planet separation is a_{⊥} = 2.18^{+0.58}_{-0.72} AU, which indicates that the planet lies beyond the snow line of the host star.
