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…

Gravitational Binary-lens Events with Prominent Effects of Lens Orbital Motion

H. Park, A. Udalski, C. Han +58

Gravitational microlensing events produced by lenses composed of binary masses are important because they provide a major channel to determine physical parameters of lenses. In thi…

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…

Flux and color variations of the doubly imaged quasar UM673

D. Ricci, A. Elyiv, F. Finet +42

With the aim of characterizing the flux and color variations of the multiple components of the gravitationally lensed quasar UM673 as a function of time, we have performed multi-ep…
