OGLE-2016-BLG-1190Lb: First Spitzer Bulge Planet Lies Near the Planet/Brown-Dwarf Boundary
Y. -H. Ryu, J. C. Yee, A. Udalski +106
We report the discovery of OGLE-2016-BLG-1190Lb, which is likely to be the first Spitzer microlensing planet in the Galactic bulge/bar, an assignation that can be confirmed by two…
OGLE-2016-BLG-0613LABb: A Microlensing Planet in a Binary System
C. Han, A. Udalski, A. Gould +37
We present the analysis of OGLE-2016-BLG-0613, for which the lensing light curve appears to be that of a typical binary-lens event with two caustic spikes but with a discontinuous…
OGLE-2017-BLG-0173Lb: Low Mass-Ratio Planet in a "Hollywood" Microlensing Event
K. -H. Hwang, A. Udalski, Y. Shvartzvald +34
We present microlensing planet OGLE-2017-BLG-0173Lb, with planet-host mass ratio either or , the lowest or among the lowest e…
OGLE-2016-BLG-0263L\lowercase{b}: Microlensing Detection of a Very Low-mass Binary Companion Through a Repeating Event Channel
C. Han, A. Udalski, A. Gould +51
We report the discovery of a planet-mass companion to the microlens OGLE-2016-BLG-0263L. Unlike most low-mass companions that were detected through perturbations to the smooth and…
A ground-based proper motion study of twelve nearby Globular Clusters
W. Narloch, J. Kaluzny, R. Poleski +3
We derive relative proper motions of stars in the fields of the globular clusters M12, NGC 6362, M4, M55, M22, NGC 6752, NGC 3201, M30, M10, NGC 362, M5, and 47 Tucanae based on da…
The First Planetary Microlensing Event with Two Microlensed Source Stars
D. P. Bennett, A. Udalski, C. Han +64
We present the analysis of microlensing event MOA-2010-BLG-117, and show that the light curve can only be explained by the gravitational lensing of a binary source star system by a…
OGLE-2016-BLG-0693LB: Probing the Brown Dwarf Desert with Microlensing
Y. -H. Ryu, A. Udalski, J. C. Yee +25
We present an analysis of microlensing event OGLE-2016-BLG-0693, based on the survey-only microlensing observations by the OGLE and KMTNet groups. In order to analyze the light cur…
OGLE-2016-BLG-0168 Binary Microlensing Event: Prediction and Confirmation of the Micorlens Parallax Effect from Space-based Observation
I. -G. Shin, A. Udalski, J. C. Yee +32
The microlens parallax is a crucial observable for conclusively identifying the nature of lens systems in microlensing events containing or composed of faint (even dark) astronomic…
OGLE-2016-BLG-1469L: Microlensing Binary Composed of Brown Dwarfs
C. Han, A. Udalski, T. Sumi +50
We report the discovery of a binary composed of two brown dwarfs, based on the analysis of the microlensing event OGLE-2016-BLG-1469. Thanks to detection of both finite-source and…
OGLE-2016-BLG-1003: First Resolved Caustic-crossing Binary-source Event Discovered by Second-generation Microlensing Surveys
Y. K. Jung, A. Udalski, I. A. Bond +50
We report the analysis of the first resolved caustic-crossing binary-source microlensing event OGLE-2016-BLG-1003. The event is densely covered by the round-the-clock observations…
OGLE-2013-BLG-0132Lb and OGLE-2013-BLG-1721Lb: Two Saturn-mass Planets Discovered around M-dwarfs
Przemek Mroz, A. Udalski, I. A. Bond +37
We present the discovery of two planetary systems consisting of a Saturn-mass planet orbiting an M-dwarf, which were detected in faint microlensing events OGLE-2013-BLG-0132 and OG…
OGLE-2013-BLG-1761Lb: A Massive Planet Around an M/K Dwarf
Y. Hirao, A. Udalski, T. Sumi +37
We report the discovery and the analysis of the planetary microlensing event, OGLE-2013-BLG-1761. There are some degenerate solutions in this event because the planetary anomaly is…
