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…

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…

OGLE-2008-BLG-510: first automated real-time detection of a weak microlensing anomaly - brown dwarf or stellar binary?

V. Bozza, M. Dominik, N. J. Rattenbury +103

The microlensing event OGLE-2008-BLG-510 is characterised by an evident asymmetric shape of the peak, promptly detected by the ARTEMiS system in real time. The skewness of the ligh…

Planetary and Other Short Binary Microlensing Events from the MOA Short Event Analysis

D. P. Bennett, T. Sumi, I. A. Bond +22

We present the analysis of four candidate short duration binary microlensing events from the 2006-2007 MOA Project short event analysis. These events were discovered as a byproduct…

MOA-2011-BLG-293Lb: A test of pure survey microlensing planet detections

J. C. Yee, Y. Shvartzvald, A. Gal-Yam +10

Because of the development of large-format, wide-field cameras, microlensing surveys are now able to monitor millions of stars with sufficient cadence to detect planets. These new…
