Reanalyses of Anomalous Gravitational Microlensing Events in the OGLE-III Early Warning System Database with Combined Data

J. Jeong, H. Park, C. Han +95

We reanalyze microlensing events in the published list of anomalous events that were observed from the OGLE lensing survey conducted during 2004-2008 period. In order to check the…

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…

One or more bound planets per Milky Way star from microlensing observations

A. Cassan, D. Kubas, J. -P. Beaulieu +39

Most known extrasolar planets (exoplanets) have been discovered using the radial velocity or transit methods. Both are biased towards planets that are relativ…

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-2005-BLG-018: Characterization of Full Physical and Orbital Parameters of a Gravitational Binary Lens

I. -G. Shin, A. Udalski, C. Han +55

We present the analysis result of a gravitational binary-lensing event OGLE-2005-BLG-018. The light curve of the event is characterized by 2 adjacent strong features and a single w…

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,…
