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-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…

MOA-bin-29b : A Microlensing Gas Giant Planet Orbiting a Low-mass Host Star

Iona Kondo, Takahiro Sumi, David P. Bennett +32

We report the discovery of a gas giant planet orbiting a low-mass host star in the microlensing event MOA-bin-29 that occurred in 2006. We find five degenerate solutions with the p…

The 2L1S/1L2S Degeneracy for Two Microlensing Planet Candidates Discovered by the KMTNet Survey in 2017

I. -G. Shin, J. C. Yee, A. Gould +46

We report two microlensing planet candidates discovered by the KMTNet survey in . However, both events have the 2L1S/1L2S degeneracy, which is an obstacle to claiming the dis…

A Wide Orbit Exoplanet OGLE-2012-BLG-0838Lb

Poleski R., Suzuki D., Udalski A. +48

We present the discovery of a planet on a very wide orbit in the microlensing event OGLE-2012-BLG-0838. The signal of the planet is well separated from the main peak of the event a…
