TL;DR: In this paper, the authors reported the discovery of the microlensing planet OGLE-2018-BLG-0740Lb. The planet was detected with a very strong signal of δ(n 2 ) 2, but the interpretation of the signal suffers from two types of degeneracies: close/wide degeneracy and ambiguity between two solutions, in which one solution requires to incorporate finite-source effects, while the other solution is consistent with a point-source interpretation.

TL;DR: In this article, the authors reported the discovery of the OGLE-2018-BLG-0532Lb, with very obvious signatures in the light curve that lead to an estimate of the planet-host mass ratio.

TL;DR: In this article, a microlensing planet OGLE-2018-BLG-0740Lb was detected with a very strong signal of Δχ^2 ~ 4630, but the interpretation of the signal suffers from two types of degeneracies.

TL;DR: In this paper, the OGLE-2016-BLG-1227 microlensing event was analyzed and it was shown that the residuals are explained by the existence of an additional widely separated heavier lens component, indicating that the lens is a wide separation planetary system rather than a free-floating planet.

TL;DR: In this paper, the discovery of a super-Jupiter in a binary was reported from the analysis of the microlensing event OGLE-2018-BLG-1700, where the complex anomaly pattern can be decomposed into two parts produced by two binary-lens events.
