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-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 ...
The First Planetary Microlensing Event with Two Microlensed Source Stars
© 2018. The American Astronomical Society. All rights reserved. We present the analysis of the microlensing event MOA-2010-BLG-117, and show that the light curve can only be explained by the gravitational lensing of a ...
