Observed Bimodality of the Einstein Crossing Times of Galactic Microlensing Events
T. Wickramasinghe, M. Struble, J. Nieusma
The OGLE data for Einstein ring crossing times, , for microlensing events toward the galactic bulge are analyzed. The analysis shows that the crossing times are bimodal, i…

Finding outlier light-curves in catalogs of periodic variable stars
P. Protopapas, J. M. Giammarco, L. Faccioli +3
We present a methodology to discover outliers in catalogs of periodic light-curves. We use cross-correlation as measure of ``similarity'' between two individual light-curves and th…

Evidence for Companion-Induced Secular Changes in the Turbulent Disk of a Be Star in the LMC MACHO Database
Mitchell F. Struble, Anthony Galatola, Lorenzo Faccioli +2
The light curve of a blue variable in the MACHO LMC database (FTS ID 78.5979.72) appeared nearly unvarying for ~4 years (quasi-flat segment) but then rapidly changed to become peri…
