Japan's Possible Contributions for Coronagraph of the Habitable Worlds Observatory (HWO)

Keigo Enya, Kenta Yoneta, Naoshi Murakami +20

In this paper, we describe Japan's possible contributions for coronagraph of the Habitable Worlds Observatory (HWO) based on our independent study. We are considering to contribute…

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…

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…

KMT-2022-BLG-0475Lb and KMT-2022-BLG-1480Lb: Microlensing ice giants detected via non-caustic-crossing channel

Cheongho Han, Chung-Uk Lee, Ian A. Bond +49

We investigate the microlensing data collected in the 2022 season from the high-cadence microlensing surveys in order to find weak signals produced by planetary companions to lense…
