KMT-2023-BLG-1431Lb: A New Microlensing Planet from a Subtle Signature

Aislyn Bell, Jiyuan Zhang, Youn Kil Jung +70

The current studies of microlensing planets are limited by small number statistics. Follow-up observations of high-magnification microlensing events can efficiently form a statisti…

OGLE-2019-BLG-0825: Constraints on the Source System and Effect on Binary-lens Parameters arising from a Five Day Xallarap Effect in a Candidate Planetary Microlensing Event

Yuki K. Satoh, Naoki Koshimoto, David P. Bennett +86

We present an analysis of microlensing event OGLE-2019-BLG-0825. This event was identified as a planetary candidate by preliminary modeling. We find that significant residuals from…

KMT-2021-BLG-1150Lb: Microlensing planet detected through a densely covered planetary-caustic signal

Cheongho Han, Youn Kil Jung, Ian A. Bond +49

Recently, there have been reports of various types of degeneracies in the interpretation of planetary signals induced by planetary caustics. In this work, we check whether such deg…

Probable brown dwarf companions detected in binary microlensing events during the 2018-2020 seasons of the KMTNet survey

Cheongho Han, Youn Kil Jung, Doeon Kim +48

We inspect the microlensing data of the KMTNet survey collected during the 2018--2020 seasons in order to find lensing events produced by binaries with brown-dwarf companions. In o…

MOA-2022-BLG-249Lb: Nearby microlensing super-Earth planet detected from high-cadence surveys

Cheongho Han, Andrew Gould, Youn Kil Jung +51

We investigate the data collected by the high-cadence microlensing surveys during the 2022 season in search for planetary signals appearing in the light curves of microlensing even…

KMT-2022-BLG-0440Lb: A New Microlensing Planet with the Central-Resonant Caustic Degeneracy Broken

Jiyuan Zhang, Weicheng Zang, Youn Kil Jung +57

We present the observations and analysis of a high-magnification microlensing planetary event, KMT-2022-BLG-0440, for which the weak and short-lived planetary signal was covered by…
