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-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…

A possible binary system of a stellar remnant in the high magnification gravitational microlensing event OGLE-2007-BLG-514

N. Miyake, A. Udalski, T. Sumi +78

We report the extremely high magnification (A > 1000) binary microlensing event OGLE-2007-BLG-514. We obtained good coverage around the double peak structure in the light curve via…

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…

A New Type of Ambiguity in the Planet and Binary Interpretations of Central Perturbations of High-Magnification Gravitational Microlensing Events

J. -Y. Choi, I. -G. Shin, C. Han +118

High-magnification microlensing events provide an important channel to detect planets. Perturbations near the peak of a high-magnification event can be produced either by a planet…
