TL;DR: In this paper, the light curves of eight binary-lensing events detected through the channel of high-magnification events during the seasons from 2007 to 2010 were analyzed, and the dependence of the degeneracy on the lensing parameters was consistent with a theoretical prediction that the degeneration becomes severe as the binary separation and the mass ratio deviate from the values of resonant caustics.

TL;DR: In this article, the authors combine long-term photometric monitoring with a previously published high-resolution spectrum taken near peak to demonstrate that this is an RS CVn variable, so that planetary microlensing is not required to explain the lightcurve deviations.

TL;DR: The OGLE-1999-BUL-19 microlensing event as discussed by the authors exhibits multiple peaks in its light curve, since the relative transverse velocity of the lens projected into the observer plane is very small.

TL;DR: In this paper, the authors combine long-term photometric monitoring with a previously published high-resolution spectrum taken near peak to demonstrate that this is an RS CVn variable, so that planetary microlensing is not required to explain the light-curve deviations.

TL;DR: The mass of the lenses giving rise to Galactic microlensing events can be constrained by measuring the relative lenssource proper motion and lens flux as mentioned in this paper, which can be separated from that of the source, companions to the source and unrelated nearby stars with high-resolution images taken when the lens and source are spatially resolved.
