Characterizing Lenses and Lensed Stars of High-Magnification Single-lens Gravitational Microlensing Events With Lenses Passing Over Source Stars

J. -Y. Choi, I. -G. Shin, S. -Y. Park +148

We present the analysis of the light curves of 9 high-magnification single-lens gravitational microlensing events with lenses passing over source stars, including OGLE-2004-BLG-254…

Microlensing Binaries Discovered through High-Magnification Channel

I. -G. Shin, J. -Y. Choi, S. -Y. Park +148

Microlensing can provide a useful tool to probe binary distributions down to low-mass limits of binary companions. In this paper, we analyze the light curves of 8 binary lensing ev…

OGLE-2008-BLG-513Lb: The Orbital Solution for a Microlensing Planet

J. C. Yee, A. Udalski, Subo Dong +14

A static binary star solution for OGLE-2008-BLG-513 has been found. The mass ratio and separation for this solution are q~0.28, s~0.86. This model has a chi^2 comparable to the chi…

MOA-2009-BLG-387Lb: A massive planet orbiting an M dwarf

Virginie Batista, A. Gould, S. Dieters +25

We report the discovery of a planet with a high planet-to-star mass ratio in the microlensing event MOA-2009-BLG-387, which exhibited pronounced deviations over a 12-day interval,…
