MOA-2010-BLG-328Lb: a sub-Neptune orbiting very late M dwarf ?

K. Furusawa, A. Udalski, T. Sumi +119

We analyze the planetary microlensing event MOA-2010-BLG-328. The best fit yields host and planetary masses of Mh = 0.11+/-0.01 M_{sun} and Mp = 9.2+/-2.2M_Earth, corresponding to…

Microlensing Discovery of a Population of Very Tight, Very Low-mass Binary Brown Dwarfs

J. -Y. Choi, C. Han, A. Udalski +121

Although many models have been proposed, the physical mechanisms responsible for the formation of low-mass brown dwarfs are poorly understood. The multiplicity properties and minim…

A Giant Planet beyond the Snow Line in Microlensing Event OGLE-2011-BLG-0251

N. Kains, R. Street, J. -Y. Choi +128

We present the analysis of the gravitational microlensing event OGLE-2011-BLG-0251. This anomalous event was observed by several survey and follow-up collaborations conducting micr…

MOA-2010-BLG-073L: An M-Dwarf with a Substellar Companion at the Planet/Brown Dwarf Boundary

R. A. Street, J. -Y. Choi, Y. Tsapras +129

We present an analysis of the anomalous microlensing event, MOA-2010-BLG-073, announced by the Microlensing Observations in Astrophysics survey on 2010-03-18. This event was remark…

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…

MOA-2010-BLG-311: A planetary candidate below the threshold of reliable detection

J. C. Yee, L. -W. Hung, I. A. Bond +123

We analyze MOA-2010-BLG-311, a high magnification (A_max>600) microlensing event with complete data coverage over the peak, making it very sensitive to planetary signals. We fit th…
