OGLE-2014-BLG-0289: Precise Characterization of a Quintuple-Peak Gravitational Microlensing Event

A. Udalski, C. Han, V. Bozza +63

We present the analysis of the binary-microlensing event OGLE-2014-BLG-0289. The event light curve exhibits very unusual five peaks where four peaks were produced by caustic crossi…

OGLE-2016-BLG-1190Lb: First Spitzer Bulge Planet Lies Near the Planet/Brown-Dwarf Boundary

Y. -H. Ryu, J. C. Yee, A. Udalski +106

We report the discovery of OGLE-2016-BLG-1190Lb, which is likely to be the first Spitzer microlensing planet in the Galactic bulge/bar, an assignation that can be confirmed by two…

OGLE-2015-BLG-1459L: The Challenges of Exo-Moon Microlensing

K. -H. Hwang, A. Udalski, I. A. Bond +57

We show that dense OGLE and KMTNet -band survey data require four bodies (sources plus lenses) to explain the microlensing light curve of OGLE-2015-BLG-1459. However, these can…

OGLE-2016-BLG-0263L\lowercase{b}: Microlensing Detection of a Very Low-mass Binary Companion Through a Repeating Event Channel

C. Han, A. Udalski, A. Gould +51

We report the discovery of a planet-mass companion to the microlens OGLE-2016-BLG-0263L. Unlike most low-mass companions that were detected through perturbations to the smooth and…

OGLE-2016-BLG-1469L: Microlensing Binary Composed of Brown Dwarfs

C. Han, A. Udalski, T. Sumi +50

We report the discovery of a binary composed of two brown dwarfs, based on the analysis of the microlensing event OGLE-2016-BLG-1469. Thanks to detection of both finite-source and…
