KMT-2024-BLG-0404L: A triple microlensing system consisting of a star, a brown dwarf, and a planet

Cheongho Han, Andrzej Udalski, Chung-Uk Lee +29

We have investigated the lensing event KMT-2024-BLG-0404. The light curve of the event exhibited a complex structure with multiple distinct features, including two prominent causti…

MOA-2022-BLG-033Lb, KMT-2023-BLG-0119Lb, and KMT-2023-BLG-1896Lb: Three low mass-ratio microlensing planets detected through dip signals

Cheongho Han, Ian A. Bond, Youn Kil Jung +45

We examined the anomalies in the light curves of the lensing events MOA-2022-BLG-033, KMT-2023-BLG-0119, and KMT-2023-BLG-1896. We conducted detailed modeling of the light curves t…

KMT-2021-BLG-0284, KMT-2022-BLG-2480, and KMT-2024-BLG-0412: Three microlensing events involving two lens masses and two source stars

Cheongho Han, Andrzej Udalski, Ian A. Bond +59

We carried out a project involving the systematic analysis of microlensing data from the Korea Microlensing Telescope Network survey. The aim of this project is to identify lensing…

Microlensing brown-dwarf companions in binaries detected during the 2022 and 2023 seasons

Cheongho Han, Ian A. Bond, Andrzej Udalski +63

Building on previous works to construct a homogeneous sample of brown dwarfs in binary systems, we investigate microlensing events detected by the Korea Microlensing Telescope Netw…

Limits of Binaries That Can Be Characterized by Gravitational Microlensing

Doeon Kim, Yoon-Hyun Ryu, Byeong-Gon Park +5

Due to the high efficiency of planet detections, current microlensing planet searches focus on high-magnification events. High-magnification events are sensitive to remote binary c…
