Systematic KMTNet Planetary Anomaly Search, Paper III: One Wide-Orbit Planet And Two Stellar Binaries

Hanyue Wang, Weicheng Zang, Wei Zhu +36

Only a few wide-orbit planets around old stars have been detected, which limits our statistical understanding of this planet population. Following the systematic search for planeta…

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-2018-BLG-1988Lb: microlensing super-Earth orbiting a low-mass disk dwarf

Cheongho Han, Andrew Gould, Michael D. Albrow +20

We reexamine high-magnification microlensing events in the previous data collected by the KMTNet survey with the aim of finding planetary signals that were not noticed before. In t…

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-0468Lb,c: two microlensing giant planets around a G-type star

Cheongho Han, Andrzej Udalski, Chung-Uk Lee +37

With the aim of interpreting anomalous lensing events with no suggested models, we conducted a project of reinvestigating microlensing data in and before the 2019 season. In this w…

Three faint-source microlensing planets detected via resonant-caustic channel

Cheongho Han, Andrzej Udalski, Doeon Kim +32

We conducted a project of reinvestigating the 2017--2019 microlensing data collected by the high-cadence surveys with the aim of finding planets that were missed due to the deviati…
