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…

Systematic Reanalysis of KMTNet microlensing events, Paper I: Updates of the Photometry Pipeline and a New Planet Candidate

Hongjing Yang, Jennifer C. Yee, Kyu-Ha Hwang +52

In this work, we update and develop algorithms for KMTNet tender-love care (TLC) photometry in order to create an new, mostly automated, TLC pipeline. We then start a project to sy…

OGLE-2014-BLG-0221Lb: A Jupiter Mass Ratio Companion Orbiting either a Late-Type Star or a Stellar Remnant

Rintaro Kirikawa, Takahiro Sumi, David P. Bennett +33

We present the analysis of microlensing event OGLE-2014-BLG-0221, a planetary candidate event discovered in 2014. The photometric light curve is best described by a binary-lens sin…

KMT-2021-BLG-1547Lb: Giant microlensing planet detected through a signal deformed by source binarity

Cheongho Han, Weicheng Zang, Youn Kil Jung +52

We investigate the previous microlensing data collected by the KMTNet survey in search of anomalous events for which no precise interpretations of the anomalies have been suggested…

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…

Brown dwarf companions in binaries detected from the 2021 season high-cadence microlensing surveys

Cheongho Han, Youn Kil Jung, Ian A. Bond +45

As a part of the project aiming to build a homogeneous sample of binary-lens (2L1S) events containing brown-dwarf (BD) companions, we investigate the 2021 season microlensing data…
