OGLE-2013-BLG-0911Lb: A Secondary on the Brown-Dwarf Planet Boundary around an M-dwarf

Shota Miyazaki, Takahiro Sumi, David P. Bennett +92

We present the analysis of the binary-lens microlensing event OGLE-2013-BLG-0911. The best-fit solutions indicate the binary mass ratio of q~0.03 which differs from that reported i…

KMT-2019-BLG-0842Lb: A Cold Planet Below the Uranus/Sun Mass Ratio

Youn Kil Jung, Andrzej Udalski, Weicheng Zang +59

We report the discovery of a cold planet with a very low planet/host mass ratio of , which is similar to the ratio of Uranus/Sun ($q=4.37 \times 10^…

Candidate Brown-dwarf Microlensing Events with Very Short Timescales and Small Angular Einstein Radii

Cheongho Han, Chung-Uk Lee, Andrzej Udalski +62

Short-timescale microlensing events are likely to be produced by substellar brown dwarfs (BDs), but it is difficult to securely identify BD lenses based on only event timescales $t…

OGLE-2018-BLG-1700L: Microlensing Planet in Binary Stellar System

Cheongho Han, Chung-Uk Lee, Andrzej Udalski +58

We report the discovery of a planet in a binary that was discovered from the analysis of the microlensing event OGLE-2018-BLG-1700. We identify the triple nature of the lens from t…

OGLE-2018-BLG-1011L\lowercase{b,c}: Microlensing Planetary System with Two Giant Planets Orbiting a Low-mass Star

Cheongho Han, David P. Bennett, Andrzej Udalski +70

We report a multiplanetary system found from the analysis of microlensing event OGLE-2018-BLG-1011, for which the light curve exhibits a double-bump anomaly around the peak. We fin…

OGLE-2015-BLG-1649Lb: A gas giant planet around a low-mass dwarf

Masayuki Nagakane, Chien-Hsiu Lee, Naoki Koshimoto +66

We report the discovery of an exoplanet in microlensing event OGLE-2015-BLG-1649. The planet/host-star mass ratio is and the projected separation normalized…
