AT2021uey: A planetary microlensing event outside the Galactic bulge

M. Ban, P. Voloshyn, R. Adomaviciene +42

We report the analysis of a planetary microlensing event AT2021uey. The event was observed outside the Galactic bulge and was alerted by both space- (Gaia) and ground-based (ZTF an…

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…

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…

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=…

Extreme Magnification Microlensing Event OGLE-2008-BLG-279: Strong Limits on Planetary Companions to the Lens Star

J. C. Yee, A. Udalski, T. Sumi +14

We analyze the extreme high-magnification microlensing event OGLE-2008-BLG-279, which peaked at a maximum magnification of A ~ 1600 on 30 May 2008. The peak of this event exhibits…

The Dark-Matter Fraction in the Elliptical Galaxy Lensing the Quasar PG1115+080

D. Pooley, S. Rappaport, J. Blackburne +3

We determine the most likely dark-matter fraction in the elliptical galaxy quadruply lensing the quasar PG1115+080 based on analyses of the X-ray fluxes of the individual images in…
