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-2015-BLG-1459L: The Challenges of Exo-Moon Microlensing
K. -H. Hwang, A. Udalski, I. A. Bond +57
We show that dense OGLE and KMTNet -band survey data require four bodies (sources plus lenses) to explain the microlensing light curve of OGLE-2015-BLG-1459. However, these can…
An Isolated Microlens Observed from K2, Spitzer and Earth
Wei Zhu, A. Udalski, C. Huang +50
We present the result of microlensing event MOA-2016-BLG-290, which received observations from the two-wheel Kepler (K2), Spitzer, as well as ground-based observatories. A joint an…
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…
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…
MOA Data Reveal a New Mass, Distance, and Relative Proper Motion for Planetary System OGLE-2015-BLG-0954L
D. P. Bennett, I. A. Bond, F. Abe +26
We present the MOA Collaboration light curve data for planetary microlensing event OGLE-2015-BLG-0954, which was previously announced in a paper by the KMTNet and OGLE Collaboratio…
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…
The Star Blended with the MOA-2008-BLG-310 Source Is Not the Exoplanet Host Star
A. Bhattacharya, D. P. Bennett, J. Anderson +7
High resolution Hubble Space Telescope (HST) image analysis of the MOA-2008-BLG-310 microlens system indicates that the excess flux at the location of the source found in the disco…
MOA-2012-BLG-505Lb: A super-Earth mass planet probably in the Galactic bulge
Masayuki Nagakane, Takahiro Sumi, Naoki Koshimoto +27
We report the discovery of a super-Earth mass planet in the microlensing event MOA-2012-BLG-505. This event has the second shortest event timescale of days whe…
