Interpretation of a short-term anomaly in the gravitational microlensing event MOA-2012-BLG-486

Interpretation of a short-term anomaly in the gravitational microlensing event MOA-2012-BLG-486

A planetary microlensing signal is generally characterized by a short-term perturbation to the standard single lensing light curve. A subset of binary-source events can produce perturbations that mimic planetary signals, thereby introducing an ambiguity between the planetary and binary-source interp...
