MOA-2010-BLG-523: "Failed Planet" = RS CVn Star

A. Gould, J. C. Yee, I. A. Bond +116

The Galactic bulge source MOA-2010-BLG-523S exhibited short-term deviations from a standard microlensing lightcurve near the peak of an Amax ~ 265 high-magnification microlensing e…

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…

Reddening and Extinction Toward the Galactic Bulge from OGLE-III: The Inner Milky Way's Rv ~ 2.5 Extinction Curve

David M. Nataf, Andrew Gould, Pascal Fouqué +11

We combine VI photometry from OGLE-III with VVV and 2MASS measurements of E(J-K_{s}) to resolve the longstanding problem of the non-standard optical extinction toward the Galactic…

MOA-2010-BLG-477Lb: constraining the mass of a microlensing planet from microlensing parallax, orbital motion and detection of blended light

E. Bachelet, I. -G. Shin, C. Han +138

Microlensing detections of cool planets are important for the construction of an unbiased sample to estimate the frequency of planets beyond the snow line, which is where giant pla…
