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…
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

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…
KMT-2021-BLG-0322: Severe degeneracy between triple-lens and higher-order binary-lens interpretations
Cheongho Han, Andrew Gould, Yuki Hirao +46
We investigate the microlensing event KMT-2021-BLG-0322, for which the light curve exhibits three distinctive sets of caustic-crossing features. It is found that the overall featur…
OGLE-2019-BLG-0304: Competing Interpretations between a Planet-binary Model and a Binary-source + Binary-lens model
Cheongho Han, Andrzej Udalski, Chung-Uk Lee +31
We analyze the microlensing event OGLE-2019-BLG-0304, whose light curve exhibits two distinctive features: a deviation in the peak region and a second bump appearing ~days…
Using Source Proper Motion to Validate Terrestrial Parallax: OGLE-2019-BLG-1058
In-Gu Shin, Jennifer C. Yee, Kyu-Ha Hwang +30
We show that because the conditions for producing terrestrial microlens parallax (TPRX; i.e., a nearby disk lens) will also tend to produce a large lens-source relative proper moti…
KMT-2018-BLG-1743: Planetary Microlensing Event Occurring on Two Source Stars
Cheongho Han, Michael D. Albrow, Sun-Ju Chung +18
We present the analysis of the microlensing event KMT-2018-BLG-1743. The light curve of the event, with a peak magnification , exhibits two anomaly features,…
Systematic KMTNet Planetary Anomaly Search, Paper II: Six New Mass-ratio Planets
Kyu-Ha Hwang, Weicheng Zang, Andrew Gould +62
We apply the automated AnomalyFinder algorithm of Paper I (Zang et al. 2021b) to 2018-2019 light curves from the covered by the six KMTNet prime fields, wi…
OGLE-2018-BLG-1185b : A Low-Mass Microlensing Planet Orbiting a Low-Mass Dwarf
Iona Kondo, Jennifer C. Yee, David P. Bennett +94
We report the analysis of planetary microlensing event OGLE-2018-BLG-1185, which was observed by a large number of ground-based telescopes and by the Space Telescope. The…
Shortest Microlensing Event with a Bound Planet: KMT-2016-BLG-2605
Yoon-Hyun Ryu, Kyu-Ha Hwang, Andrew Gould +17
KMT-2016-BLG-2605, with planet-host mass ratio , has the shortest Einstein timescale, $t_\e = 3.41\pm 0.13\,$days, of any planetary microlensing event to date. Th…
Three microlensing planets with no caustic-crossing features
Cheongho Han, Andrzej Udalski, Doeon Kim +31
We search for microlensing planets with signals exhibiting no caustic-crossing features, considering the possibility that such signals may be missed due to their weak and featurele…
KMT-2019-BLG-1715: planetary microlensing event with three lens masses and two source stars
Cheongho Han, Andrzej Udalski, Doeone Kim +61
We investigate the gravitational microlensing event KMT-2019-BLG-1715, of which light curve shows two short-term anomalies from a caustic-crossing binary-lensing light curve: one w…
Systematic KMTNet Planetary Anomaly Search, Paper I: OGLE-2019-BLG-1053Lb, A Buried Terrestrial Planet
Weicheng Zang, Kyu-Ha Hwang, Andrzej Udalski +69
In order to exhume the buried signatures of "missing planetary caustics" in the KMTNet data, we conducted a systematic anomaly search to the residuals from point-source point-lens…
