Microlensing Results Challenge the Core Accretion Runaway Growth Scenario for Gas Giants
Daisuke Suzuki, David P. Bennett, Shigeru Ida +14
We compare the planet-to-star mass-ratio distribution measured by gravitational microlensing to core accretion theory predictions from population synthesis models. The core accreti…
First assessment of the binary lens OGLE-2015_BLG-0232
E. Bachelet, V. Bozza, C. Han +51
We present an analysis of the microlensing event OGLE-2015-BLG-0232. This event is challenging to characterize for two reasons. First, the light curve is not well sampled during th…
Two new free-floating or wide-orbit planets from microlensing
P. Mroz, A. Udalski, D. P. Bennett +57
Planet formation theories predict the existence of free-floating planets that have been ejected from their parent systems. Although they emit little or no light, they can be detect…
OGLE-2015-BLG-1670Lb: A Cold Neptune beyond the Snow Line in the Provisional WFIRST Microlensing Survey Field
Clément Ranc, David P. Bennett, Yuki Hirao +56
We present the analysis of the microlensing event OGLE-2015-BLG-1670, detected in a high-extinction field, very close to the Galactic plane. Due to the dust extinction along the li…
OGLE-2017-BLG-0039: Microlensing Event with Light from the Lens Identified from Mass Measurement
C. Han, Y. K. Jung, A. Udalski +58
We present the analysis of the caustic-crossing binary microlensing event OGLE-2017-BLG-0039. Thanks to the very long duration of the event, with an event time scale $t_{\rm E}\sim…
MOA-2016-BLG-319Lb: Microlensing Planet Subject to Rare Minor-Image Perturbation Degeneracy in Determining Planet Parameter
Cheongho Han, Ian A. Bond, Andrew Gould +42
We present the analysis of the planetary microlensing event MOA-2016-BLG-319. The event light curve is characterized by a brief ( days) anomaly near the peak produced by mi…
A Planetary Microlensing Event with an Unusually Red Source Star: MOA-2011-BLG-291
David P. Bennett, Andrzej Udalski, Ian A. Bond +43
We present the analysis of planetary microlensing event MOA-2011-BLG-291, which has a mass ratio of and a source star that is redder (or brighter) than…
OGLE-2014-BLG-0962 and the First Statistical Validation of Bayesian Priors for Galactic Microlensing
Yutong Shan, Jennifer C. Yee, Andrzej Udalski +46
OGLE-2014-BLG-0962 (OB140962) is a stellar binary microlensing event that was well-covered by observations from the Spitzer satellite as well as ground-based surveys. Modelling yie…
A study of light travel time effect in short-period MOA eclipsing binaries via eclipse timing
M. C. A. Li, N. J. Rattenbury, I. A. Bond +23
A sample of 542 eclipsing binaries (EBs) with periods shorter than 2 d were selected from the Microlensing Observations in Astrophysics (MOA) EB catalogue (Li et al. 2017) for ecli…
MOA-2015-BLG-337: A Planetary System with a Low-mass Brown Dwarf/Planetary Boundary Host, or a Brown Dwarf Binary
S. Miyazaki, T. Sumi, D. P. Bennett +59
We report the discovery and the analysis of the short timescale binary-lens microlensing event, MOA-2015-BLG-337. The lens system could be a planetary system with a very low mass h…
OGLE-2017-BLG-0482Lb: A Microlensing Super-Earth Orbiting a Low-mass Host Star
C. Han, Y. Hirao, A. Udalski +62
We report the discovery of a planetary system in which a super-earth orbits a late M-dwarf host. The planetary system was found from the analysis of the microlensing event OGLE-201…
The WFIRST Exoplanet Microlensing Survey
David P. Bennett, Rachel Akeson, Jay Anderson +71
The Wide Field Infrared Survey Telescope (WFIRST) was the top ranked large space mission in the 2010 New Worlds, New Horizons decadal survey, and it was formed by merging the scien…
White Paper: Exoplanetary Microlensing from the Ground in the 2020s
Jennifer C. Yee, Jay Anderson, Rachel Akeson +25
Microlensing can access planet populations that no other method can probe: cold wide-orbit planets beyond the snow line, planets in both the Galactic bulge and disk, and free float…
A Likely Detection of a Two-Planet System in a Low Magnification Microlensing Event
D. Suzuki, D. P. Bennett, A. Udalski +37
We report on the analysis of a microlensing event OGLE-2014-BLG-1722 that showed two distinct short term anomalies. The best fit model to the observed light curves shows that the t…
Spitzer Microlensing Parallax for OGLE-2016-BLG-1067: a sub-Jupiter Orbiting an M-dwarf in the Disk
S. Calchi Novati, D. Suzuki, A. Udalski +65
We report the discovery of a sub-Jupiter mass planet orbiting beyond the snow line of an M-dwarf most likely in the Galactic disk as part of the joint Spitzer and ground-based moni…
OGLE-2014-BLG-0289: Precise Characterization of a Quintuple-Peak Gravitational Microlensing Event
A. Udalski, C. Han, V. Bozza +63
We present the analysis of the binary-microlensing event OGLE-2014-BLG-0289. The event light curve exhibits very unusual five peaks where four peaks were produced by caustic crossi…
