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…
