A Candidate High-velocity Exoplanet System in the Galactic Bulge

A Candidate High-velocity Exoplanet System in the Galactic Bulge

We present an analysis of adaptive optics images from the Keck I telescope of the microlensing event MOA-2011-BLG-262. The original discovery paper by Bennett et al. reports two possibilities for the lens system: a nearby gas giant lens with an exomoon companion or a very low-mass star with a planet...
