OGLE-2017-BLG-0039: Microlensing Event with Light from the Lens Identified from Mass Measurement

C. Han, Y. K. Jung, A. Udalski +58

We present the analysis of the caustic-crossing binary microlensing event OGLE-2017-BLG-0039. Thanks to the very long duration of the event, with an event time scale $t_{\rm E}\sim…

A study of light travel time effect in short-period MOA eclipsing binaries via eclipse timing

M. C. A. Li, N. J. Rattenbury, I. A. Bond +23

A sample of 542 eclipsing binaries (EBs) with periods shorter than 2 d were selected from the Microlensing Observations in Astrophysics (MOA) EB catalogue (Li et al. 2017) for ecli…

OGLE-2014-BLG-0289: Precise Characterization of a Quintuple-Peak Gravitational Microlensing Event

A. Udalski, C. Han, V. Bozza +63

We present the analysis of the binary-microlensing event OGLE-2014-BLG-0289. The event light curve exhibits very unusual five peaks where four peaks were produced by caustic crossi…

Ground-based parallax confirmed by Spitzer: binary microlensing event MOA-2015-BLG-020

Tianshu Wang, Wei Zhu, Shude Mao +83

We present the analysis of the binary gravitational microlensing event MOA-2015-BLG-020. The event has a fairly long timescale (about 63 days) and thus the light curve deviates sig…

The First Eclipsing Binary Catalogue from the MOA-II database

M. C. A. Li, N. J. Rattenbury, A. Bond +25

We present the first catalogue of eclipsing binaries in two MOA fields towards the Galactic bulge, in which over 8,000 candidates, mostly contact and semi-detached binaries of peri…

OGLE-2016-BLG-1469L: Microlensing Binary Composed of Brown Dwarfs

C. Han, A. Udalski, T. Sumi +50

We report the discovery of a binary composed of two brown dwarfs, based on the analysis of the microlensing event OGLE-2016-BLG-1469. Thanks to detection of both finite-source and…
