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…
Kmt-2016-blg-1397b: Kmtnet-only discovery of a microlens giant planet
Weicheng Zang, Kyu-Ha Hwang, Hyoun-Woo Kim +20
We report the discovery of a giant planet in the KMT-2016-BLG-1397 microlensing event, which was found by The Korea Microlensing Telescope Network (KMTNet) alone. The time scale of…
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…
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…
KMT-2017-BLG-0165Lb: A Super-Neptune mass planet Orbiting a Sun-like Host Star
Youn Kil Jung, Andrew Gould, Weicheng Zang +22
We report the discovery of a low mass-ratio planet , i.e., 2.5 times higher than the Neptune/Sun ratio. The planetary system was discovered from the analysi…
OGLE-2014-BLG-1186: gravitational microlensing providing evidence for a planet orbiting the foreground star or for a close binary source?
M. Dominik, E. Bachelet, V. Bozza +40
(abridged) Using the particularly long gravitational microlensing event OGLE-2014-BLG-1186 with a time-scale ~ 300 d, we present a methodology for identifying the na…
