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…

Chemical evolution of the Galactic bulge as traced by microlensed dwarf and subgiant stars. V. Evidence for a wide age distribution and a complex MDF

T. Bensby, J. C. Yee, S. Feltzing +20

Based on high-resolution spectra obtained during gravitational microlensing events we present a detailed elemental abundance analysis of 32 dwarf and subgiant stars in the Galactic…

A New Galactic Extinction Map in High Ecliptic Latitudes

Tsunehito Kohyama, Hiroshi Shibai, Misato Fukagawa +2

In this study, we derived a galactic extinction map in high ecliptic latitudes for |β| > 30 degrees. The dust temperature distribution was derived from the intensities at 100 and 1…

MOA-2010-BLG-523: "Failed Planet" = RS CVn Star

A. Gould, J. C. Yee, I. A. Bond +116

The Galactic bulge source MOA-2010-BLG-523S exhibited short-term deviations from a standard microlensing lightcurve near the peak of an Amax ~ 265 high-magnification microlensing e…

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…

Using Orbital Effects to Break the Close/wide Degeneracy in Binary-lens Microlensing Events

I. -G. Shin, T. Sumi, A. Udalski +37

Microlensing can provide an important tool to study binaries, especially those composed of faint or dark objects. However, accurate analysis of binary-lens light curves is often ha…

Microlensig Binaries with Candidate Brown Dwarf Companions

I. -G. Shin, C. Han, A. Gould +152

Brown dwarfs are important objects because they may provide a missing link between stars and planets, two populations that have dramatically different formation history. In this pa…

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…

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…
