The First Circumbinary Planet Found by Microlensing: OGLE-2007-BLG-349L(AB)c

D. P. Bennett, S. H. Rhie, A. Udalski +79

We present the analysis of the first circumbinary planet microlensing event, OGLE-2007-BLG-349. This event has a strong planetary signal that is best fit with a mass ratio of $q \a…

MOA-2007-BLG-197: Exploring the brown dwarf desert

C. Ranc, A. Cassan, M. D. Albrow +48

We present the analysis of MOA-2007-BLG-197Lb, the first brown dwarf companion to a Sun-like star detected through gravitational microlensing. The event was alerted and followed-up…

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…

OGLE-2011-BLG-0265Lb: a Jovian Microlensing Planet Orbiting an M Dwarf

J. Skowron, I. -G. Shin, A. Udalski +121

We report the discovery of a Jupiter-mass planet orbiting an M-dwarf star that gave rise to the microlensing event OGLE-2011-BLG-0265. Such a system is very rare among known planet…

A Sub-Earth-Mass Moon Orbiting a Gas Giant Primary or a High Velocity Planetary System in the Galactic Bulge

D. P. Bennett, V. Batista, I. A. Bond +90

We present the first microlensing candidate for a free-floating exoplanet-exomoon system, MOA-2011-BLG-262, with a primary lens mass of M_host ~ 4 Jupiter masses hosting a sub-Eart…

MOA-2010-BLG-328Lb: a sub-Neptune orbiting very late M dwarf ?

K. Furusawa, A. Udalski, T. Sumi +119

We analyze the planetary microlensing event MOA-2010-BLG-328. The best fit yields host and planetary masses of Mh = 0.11+/-0.01 M_{sun} and Mp = 9.2+/-2.2M_Earth, corresponding to…
