Description

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 to the smooth and symmetric light curves produced by the primary, the companion was discovered through the channel of a repeating event, in which the companion itself produced its own single-mass light curve after the event produced by the primary had ended. Thanks to the continuous coverage of the second peak by high-cadence surveys,...
