OGLE-2019-BLG-0362Lb: A super-Jovian-mass planet around a low-mass star

/ Abstract
: We 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 ∆ χ 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.
