Systematic KMTNet Planetary Anomaly Search. VIII. Complete Sample of 2019 Subprime Field Planets

Youn Kil Jung, Weicheng Zang, Hanyue Wang +41

We complete the publication of all microlensing planets (and ``possible planets'') identified by the uniform approach of the KMT AnomalyFinder system in the 21 KMT subprime fields…

MOA-2020-BLG-208Lb: Cool Sub-Saturn Planet Within Predicted Desert

Greg Olmschenk, David P. Bennett, Ian A. Bond +74

We analyze the MOA-2020-BLG-208 gravitational microlensing event and present the discovery and characterization of a new planet, MOA-2020-BLG-208Lb, with an estimated sub-Saturn ma…

OGLE-2013-BLG-0911Lb: A Secondary on the Brown-Dwarf Planet Boundary around an M-dwarf

Shota Miyazaki, Takahiro Sumi, David P. Bennett +92

We present the analysis of the binary-lens microlensing event OGLE-2013-BLG-0911. The best-fit solutions indicate the binary mass ratio of q~0.03 which differs from that reported i…

On the long cycle variability of the Algol OGLE-LMC-DPV-065 and its stellar, orbital and disk parameters

R. E. Mennickent, M. Cabezas, G. Djurašević +13

OGLE-LMC-DPV-065 is an interacting binary whose double-hump long photometric cycle remains hitherto unexplained. We analyze photometric time series available in archive datasets sp…

OGLE-2017-BLG-1186: first application of asteroseismology and Gaussian processes to microlensing

Shun-Sheng Li, Weicheng Zang, Andrzej Udalski +102

We present the analysis of the event OGLE-2017-BLG-1186 from the 2017 Spitzer microlensing campaign. This is a remarkable microlensing event because its source is photometrically b…

Spitzer Microlensing Program as a Probe for Globular Cluster Planets. Analysis of OGLE-2015-BLG-0448

Radosław Poleski, Wei Zhu, Grant W. Christie +83

The microlensing event OGLE-2015-BLG-0448 was observed by Spitzer and lay within the tidal radius of the globular cluster NGC 6558. The event had moderate magnification and was int…

Mass Measurements of Isolated Objects from Space-based Microlensing

Wei Zhu, S. Calchi Novati, A. Gould +78

We report on the mass and distance measurements of two single-lens events from the 2015 \emph{Spitzer} microlensing campaign. With both finite-source effect and microlens parallax…

A Terrestrial Planet in a ~1 AU Orbit Around One Member of a ~15 AU Binary

A. Gould, A. Udalski, I. -G. Shin +61

We detect a cold, terrestrial planet in a binary-star system using gravitational microlensing. The planet has low mass (2 Earth masses) and lies projected at ~ 0.8 a…

MOA-2013-BLG-220Lb: Massive Planetary Companion to Galactic-Disk Host

J. C. Yee, C. Han, A. Gould +70

We report the discovery of MOA-2013-BLG-220Lb, which has a super-Jupiter mass ratio relative to its host. The proper motion, $μ=12.5\pm 1\, {\rm mas}…

A Super-Jupiter orbiting a late-type star: A refined analysis of microlensing event OGLE-2012-BLG-0406

Y. Tsapras, J. -Y. Choi, R. A. Street +122

We present a detailed analysis of survey and follow-up observations of microlensing event OGLE-2012-BLG-0406 based on data obtained from 10 different observatories. Intensive cover…

Microlensing Discovery of a Tight, Low Mass-ratio Planetary-mass Object around an Old, Field Brown Dwarf

C. Han, Y. K. Jung, A. Udalski +67

Observations of accretion disks around young brown dwarfs have led to the speculation that they may form planetary systems similar to normal stars. While there have been several de…

Gravitational Binary-lens Events with Prominent Effects of Lens Orbital Motion

H. Park, A. Udalski, C. Han +58

Gravitational microlensing events produced by lenses composed of binary masses are important because they provide a major channel to determine physical parameters of lenses. In thi…

The second multiple-planet system discovered by microlensing: OGLE-2012-BLG-0026Lb, c, a pair of jovian planets beyond the snow line

C. Han, A. Udalski, J. -Y. Choi +33

We report the discovery of a planetary system from observation of the high-magnification microlensing event OGLE-2012-BLG-0026. The lensing light curve exhibits a complex central p…
