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…

An Isolated Microlens Observed from K2, Spitzer and Earth

Wei Zhu, A. Udalski, C. Huang +50

We present the result of microlensing event MOA-2016-BLG-290, which received observations from the two-wheel Kepler (K2), Spitzer, as well as ground-based observatories. A joint an…

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…

Ground-based parallax confirmed by Spitzer: binary microlensing event MOA-2015-BLG-020

Tianshu Wang, Wei Zhu, Shude Mao +83

We present the analysis of the binary gravitational microlensing event MOA-2015-BLG-020. The event has a fairly long timescale (about 63 days) and thus the light curve deviates sig…

The First Planetary Microlensing Event with Two Microlensed Source Stars

D. P. Bennett, A. Udalski, C. Han +64

We present the analysis of microlensing event MOA-2010-BLG-117, and show that the light curve can only be explained by the gravitational lensing of a binary source star system by a…
