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…
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…
KMT-2016-BLG-2052L: Microlensing Binary Composed of M Dwarfs Revealed from a Very Long Time-scale Event
Cheongho Han, Youn Kil Jung, Yossi Shvartzvald +26
We present the analysis of a binary microlensing event KMT-2016-BLG-2052, for which the lensing-induced brightening of the source star lasted for 2 seasons. We determine the lens m…
The Korea Microlensing Telescope Network (KMTNet) Alert Algorithm and Alert System
Hyoun-Woo Kim, Kyu-Ha Hwang, Yossi Shvartzvald +17
We describe a new microlensing-event alert algorithm that is tailored to the Korea Microlensing Telescope Network (KMTNet) multi-observatory system. The algorithm focuses on detect…
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…
KMT-2016-BLG-1820 and KMT-2016-BLG-2142: Two Microlensing Binaries Composed of Planetary-mass Companions and Very-Low-Mass Primaries
Youn Kil Jung, Kyu-Ha Hwang, Yoon-Hyun Ryu +17
We present the analyses of two short-timescale microlensing events, KMT-2016-BLG-1820 and KMT-2016-BLG-2142. In both light curves, the brief anomali…
KMT-2016-BLG-1107: A New Hollywood-Planet Close/Wide Degeneracy
Kyu-Ha Hwang, Yoon-Hyun Ryu, Hyoun-Woo Kim +17
We show that microlensing event KMT-2016-BLG-1107 displays a new type of degeneracy between wide-binary and close-binary Hollywood events in which a giant-star source envelops the…
Microlensing Parallax for OGLE-2017-BLG-0896 Reveals a Counter-Rotating Low-Mass Brown Dwarf
Yossi Shvartzvald, Jennifer C. Yee, Jan Skowron +63
The kinematics of isolated brown dwarfs in the Galaxy, beyond the solar neighborhood, is virtually unknown. Microlensing has the potential to probe this hidden population, as it ca…
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…
