TL;DR: In this article, the authors presented the discovery and characterization of two ultra-short microlensing events identified in data from the Optical Gravitational Lensing Experiment (OGLE) survey, which may have been caused by free-floating or wide-orbit planets.
Journal ArticleDOI
Reanalysis of the Gravitational Microlensing Event MACHO-97-BLG-41 based on Combined Data
TL;DR: In this article, the authors proposed two different interpretations of the lens from independent analyses based on two different data sets: one interpreted the event as produced by a circumbinary planetary system and the other explained the light curve with only a binary system by introducing orbital motion of lens.
Journal ArticleDOI
