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^…
Kojima-1Lb Is a Mildly Cold Neptune around the Brightest Microlensing Host Star
A. Fukui, D. Suzuki, N. Koshimoto +56
We report the analysis of additional multiband photometry and spectroscopy and new adaptive optics (AO) imaging of the nearby planetary microlensing event TCP J05074264+2447555 (Ko…
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…
Bayesian Approach for Determining Microlens System Properties with High-Angular-Resolution Follow-up Imaging
Naoki Koshimoto, David P. Bennett, Daisuke Suzuki
We present the details of the Bayesian analysis on the planetary microlensing event MOA-2016-BLG-227, whose excess flux is likely due to a source/lens companion or an unrelated amb…
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…
