Using Orbital Effects to Break the Close/wide Degeneracy in Binary-lens Microlensing Events

I. -G. Shin, T. Sumi, A. Udalski +37

Microlensing can provide an important tool to study binaries, especially those composed of faint or dark objects. However, accurate analysis of binary-lens light curves is often ha…

The second multiple-planet system discovered by microlensing: OGLE-2012-BLG-0026Lb, c, a pair of jovian planets beyond the snow line

C. Han, A. Udalski, J. -Y. Choi +33

We report the discovery of a planetary system from observation of the high-magnification microlensing event OGLE-2012-BLG-0026. The lensing light curve exhibits a complex central p…

Microlensig Binaries with Candidate Brown Dwarf Companions

I. -G. Shin, C. Han, A. Gould +152

Brown dwarfs are important objects because they may provide a missing link between stars and planets, two populations that have dramatically different formation history. In this pa…

Further Evidence that Quasar X-Ray Emitting Regions Are Compact: X-Ray and Optical Microlensing in the Lensed Quasar Q J0158-4325

Christopher W. Morgan, Laura J. Hainline, Bin Chen +9

We present four new seasons of optical monitoring data and six epochs of X-ray photometry for the doubly-imaged lensed quasar Q J0158-4325. The high-amplitude, short-period microle…

A New Type of Ambiguity in the Planet and Binary Interpretations of Central Perturbations of High-Magnification Gravitational Microlensing Events

J. -Y. Choi, I. -G. Shin, C. Han +118

High-magnification microlensing events provide an important channel to detect planets. Perturbations near the peak of a high-magnification event can be produced either by a planet…

Characterizing Low-Mass Binaries From Observation of Long Time-scale Caustic-crossing Gravitational Microlensing Events

I. -G. Shin, C. Han, J. -Y. Choi +119

Despite astrophysical importance of binary star systems, detections are limited to those located in small ranges of separations, distances, and masses and thus it is necessary to u…

Is Quasar Optical Variability a Damped Random Walk?

Ying Zu, C. S. Kochanek, Szymon Kozłowski +1

The damped random walk (DRW) model is increasingly used to model the variability in quasar optical light curves, but it is still uncertain whether the DRW model provides an adequat…

MOA-2011-BLG-293Lb: A test of pure survey microlensing planet detections

J. C. Yee, Y. Shvartzvald, A. Gal-Yam +10

Because of the development of large-format, wide-field cameras, microlensing surveys are now able to monitor millions of stars with sufficient cadence to detect planets. These new…
