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…

Precision measurement of a brown dwarf mass in a binary system in the microlensing event OGLE-2019-BLG-0033/MOA-2019-BLG-035

A. Herald, A. Udalski, V. Bozza +89

Context. Brown dwarfs are poorly understood transition objects between stars and planets, with several competing mechanisms having been proposed for their formation. Mass measureme…

Single-lens mass measurement in the high-magnification microlensing event Gaia19bld located in the Galactic disc

K. A. Rybicki, Ł. Wyrzykowski, E. Bachelet +66

We present the photometric analysis of Gaia19bld, a high-magnification () microlensing event located in the southern Galactic plane, which exhibited finite source and m…

KMT-2021-BLG-0912Lb: A microlensing super Earth around a K-type star

Cheongho Han, Ian A. Bond, Jennifer C. Yee +55

The light curve of the microlensing event KMT-2021-BLG-0912 exhibits a very short anomaly relative to a single-lens single-source form. We investigate the light curve for the purpo…

OGLE-2019-BLG-0960Lb: The Smallest Microlensing Planet

Jennifer C. Yee, Weicheng Zang, Andrzej Udalski +80

We report the analysis of OGLE-2019-BLG-0960, which contains the smallest mass-ratio microlensing planet found to date (q = 1.2--1.6 x 10^{-5} at 1-sigma). Although there is substa…

Spitzer Microlensing parallax reveals two isolated stars in the Galactic bulge

Weicheng Zang, Yossi Shvartzvald, Tianshu Wang +90

We report the mass and distance measurements of two single-lens events from the 2017 Spitzer microlensing campaign. The ground-based observations yield the detection of finite-sour…

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…
