A Sub-Earth-Mass Moon Orbiting a Gas Giant Primary or a High Velocity Planetary System in the Galactic Bulge

D. P. Bennett, V. Batista, I. A. Bond +90

We present the first microlensing candidate for a free-floating exoplanet-exomoon system, MOA-2011-BLG-262, with a primary lens mass of M_host ~ 4 Jupiter masses hosting a sub-Eart…

MOA-2011-BLG-293Lb: First Microlensing Planet possibly in the Habitable Zone

V. Batista, J. -P. Beaulieu, A. Gould +6

We used Keck adaptive optics observations to identify the first planet discovered by microlensing to lie in or near the habitable zone, i.e., at projected separation $r_\perp=1.1\p…

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…

The Microlensing Event Rate and Optical Depth Toward the Galactic Bulge from MOA-II

T. Sumi, D. P. Bennett, I. A. Bond +19

We present measurements of the microlensing optical depth and event rate toward the Galactic Bulge based on two years of the MOA-II survey. This sample contains ~1000 microlensing…

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…
