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^…
OGLE-2016-BLG-1227L: A Wide-separation Planet from a Very Short-timescale Microlensing Event
Cheongho Han, Andrzej Udalski, Andrew Gould +30
We present the analysis of the microlensing event OGLE-2016-BLG-1227. The light curve of this short-duration event appears to be a single-lens event affected by severe finite-sourc…
OGLE-2015-BLG-1771Lb: A Microlens Planet Orbiting an Ultracool Dwarf?
Xiangyu Zhang, Weicheng Zang, Andrzej Udalski +31
We report the discovery and the analysis of the short (tE < 5 days) planetary microlensing event, OGLE-2015-BLG-1771. The event was discovered by the Optical Gravitational Lensing…
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…
KMT-2016-BLG-1836Lb: A Super-Jovian Planet From A High-Cadence Microlensing Field
Hongjing Yang, Xiangyu Zhang, Kyu-Ha Hwang +24
We report the discovery of a super-Jovian planet in the microlensing event KMT-2016-BLG-1836, which was found by the Korea Microlensing Telescope Network's high-cadence observation…
