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…
A terrestrial-mass rogue planet candidate detected in the shortest-timescale microlensing event
P. Mroz, R. Poleski, A. Gould +27
Some low-mass planets are expected to be ejected from their parent planetary systems during early stages of planetary system formation. According to planet-formation theories, such…
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…
Spitzer Microlensing Parallax for OGLE-2016-BLG-1067: a sub-Jupiter Orbiting an M-dwarf in the Disk
S. Calchi Novati, D. Suzuki, A. Udalski +65
We report the discovery of a sub-Jupiter mass planet orbiting beyond the snow line of an M-dwarf most likely in the Galactic disk as part of the joint Spitzer and ground-based moni…
Frequency of Solar-Like Systems and of Ice and Gas Giants Beyond the Snow Line from High-Magnification Microlensing Events in 2005-2008
A. Gould, Subo Dong, B. S. Gaudi +14
We present the first measurement of planet frequency beyond the "snow line" for planet/star mass-ratios[-4.5<log q<-2]: d^2 N/dlog q/dlog s=(0.36+-0.15)/dex^2 at mean mass ratio q=…
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…
