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…
An Earth-mass Planet in a Time of Covid-19: KMT-2020-BLG-0414Lb
Weicheng Zang, Cheongho Han, Iona Kondo +56
We report the discovery of KMT-2020-BLG-0414Lb, with a planet-to-host mass ratio ---- at , which is the lowest mass-ratio micro…
Sub-Saturn Planet MOA-2008-BLG-310Lb: Likely To Be In The Galactic Bulge
Julia Janczak, A. Fukui, Subo Dong +13
We report the detection of sub-Saturn-mass planet MOA-2008-BLG-310Lb and argue that it is the strongest candidate yet for a bulge planet. Deviations from the single-lens fit are sm…
Distinguishing between Planetary and Binary Interpretations of Microlensing Central Perturbations under Severe Finite-Source Effect
Cheongho Han
In the current strategy of microlensing planet searches focusing on high-magnification events, wide and close binaries pose important sources of contamination that imitates planeta…
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…
The Effect of Luminous Lens Blending in Gravitational Microlensing Experiments
Seunghun Lee, Cheongho Han
The most important uncertainty in the results of gravitational microlensing experiments comes from the difficulties of photometry caused by blending of source stars. Recently Nemir…
