Beyond Caustic Crossings: Properties of Binary Microlensing Light Curves
Binary microlensing light curves have a variety of morphologies.Many are indistinguishable from point-lens light curves.Of those that deviate from the point-lens form, caustic crossing light curves have tended to dominate identified binary-lens events.Other distinctive signatures of binary lenses include significant asymmetry, multiple peaks, and repeating events.We have quantified, using high-resolution …
