A Wide Orbit Exoplanet OGLE-2012-BLG-0838Lb
Poleski R., Suzuki D., Udalski A. +48
We present the discovery of a planet on a very wide orbit in the microlensing event OGLE-2012-BLG-0838. The signal of the planet is well separated from the main peak of the event a…
A companion on the planet/brown dwarf mass boundary on a wide orbit discovered by gravitational microlensing
R. Poleski, A. Udalski, I. A. Bond +40
We present the discovery of a substellar companion to the primary host lens in the microlensing event MOA-2012-BLG-006. The companion-to-host mass ratio is 0.016, corresponding to…
Microlensing Discovery of a Population of Very Tight, Very Low-mass Binary Brown Dwarfs
J. -Y. Choi, C. Han, A. Udalski +121
Although many models have been proposed, the physical mechanisms responsible for the formation of low-mass brown dwarfs are poorly understood. The multiplicity properties and minim…
Frequency of Solar-Like Systems and of Ice and Gas Giants Beyond the Snow Line from High-Magnification Microlensing Events in 2005-2008
A. Gould, Subo Dong, B. S. Gaudi +14
We present the first measurement of planet frequency beyond the "snow line" for planet/star mass-ratios[-4.5<log q<-2]: d^2 N/dlog q/dlog s=(0.36+-0.15)/dex^2 at mean mass ratio q=…
EROS 2 proper motion survey: Constraints on the halo white dwarfs
B. Goldman, C. Afonso, Ch. Alard +9
We are conducting a 377-square-degree proper motion survey in the ~V and I bands in order to determine the cool white dwarf contribution to the Galactic dark matter. Using the 250…
Observation of Microlensing towards the Galactic Spiral Arms. EROS II 3 year survey
EROS Collaboration
We present an analysis of the light curves of 9.1 million stars observed during three seasons by EROS (Experience de Recherche d'Objets Sombres), in the Galactic plane away from th…
