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…

OGLE-2011-BLG-0265Lb: a Jovian Microlensing Planet Orbiting an M Dwarf

J. Skowron, I. -G. Shin, A. Udalski +121

We report the discovery of a Jupiter-mass planet orbiting an M-dwarf star that gave rise to the microlensing event OGLE-2011-BLG-0265. Such a system is very rare among known planet…

A Sub-Earth-Mass Moon Orbiting a Gas Giant Primary or a High Velocity Planetary System in the Galactic Bulge

D. P. Bennett, V. Batista, I. A. Bond +90

We present the first microlensing candidate for a free-floating exoplanet-exomoon system, MOA-2011-BLG-262, with a primary lens mass of M_host ~ 4 Jupiter masses hosting a sub-Eart…

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=…

The PLANET microlensing campaign: Implications for planets around galactic disk and bulge stars

M. Dominik, M. D. Albrow, J. -P. Beaulieu +17

With round-the-clock monitoring of galactic bulge microlensing events, the PLANET experiment constrains the abundance and can yield the discovery of planets down to the mass of ear…
