OGLE-2016-BLG-1003: First Resolved Caustic-crossing Binary-source Event Discovered by Second-generation Microlensing Surveys
We report the analysis of the first resolved caustic-crossing binary-source microlensing event OGLE-2016-BLG-1003. The event is densely covered by the round-the-clock observations of three surveys. The light curve is ...
OGLE-2016-BLG-1469L: Microlensing Binary Composed of Brown Dwarfs
© 2017. The American Astronomical Society. All rights reserved. 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 the detection ...
OGLE-2015-BLG-1459L: The Challenges of Exo-Moon Microlensing
We show that dense OGLE and KMTNet $I$-band survey data require four bodies (sources plus lenses) to explain the microlensing light curve of OGLE-2015-BLG-1459. However, these can equally well consist of three lenses ...
OGLE-2016-BLG-1190Lb: First Spitzer Bulge Planet Lies Near the Planet/Brown-Dwarf Boundary
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 epochs of high-resolution imaging of the ...
Ground-based Parallax Confirmed by Spitzer: Binary Microlensing Event MOA-2015-BLG-020
© 2017. The American Astronomical Society. All rights reserved.. We present the analysis of the binary gravitational microlensing event MOA-2015-BLG-020. The event has a fairly long timescale (∼63 days) and thus the light ...
OGLE-2016-BLG-0263Lb: Microlensing Detection of a Very Low-mass Binary Companion through a Repeating Event Channel
© 2017. The American Astronomical Society. All rights reserved. We report the discovery of a planet-mass companion to the microlens OGLE-2016-BLG-0263L. Unlike most lowmass companions that were detected through perturbations ...
