OGLE-2018-BLG-0971, MOA-2023-BLG-065, and OGLE-2023-BLG-0136: Microlensing events with prominent orbital effects

Cheongho Han, Andrzej Udalski, Ian A. Bond +60

We undertake a project to reexamine microlensing data gathered from high-cadence surveys. The aim of the project is to reinvestigate lensing events with light curves exhibiting int…

Gravitational-wave Electromagnetic Counterpart Korean Observatory (GECKO): GECKO Follow-up Observation of GW190425

Gregory S. H. Paek, Myungshin Im, Joonho Kim +13

One of the keys to the success of multimessenger astronomy is the rapid identification of the electromagnetic wave counterpart, kilonova (KN), of the gravitational-wave (GW) event.…

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…

Systematic KMTNet Planetary Anomaly Search. X. Complete Sample of 2017 Prime-Field Planets

Yoon-Hyun Ryu, Andrzej Udalski, Jennifer C. Yee +38

We complete the analysis of planetary candidates found by the KMT AnomalyFinder for the 2017 prime fields that cover . We report 3 unambiguous planets: OGLE-2…

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-2010Lb, KMT-2022-BLG-0371Lb, and KMT-2022-BLG-1013Lb: Three microlensing planets detected via partially covered signals

Cheongho Han, Chung-Uk Lee, Weicheng Zang +25

We inspect 4 microlensing events KMT-2021-BLG-1968, KMT-2021-BLG-2010, KMT-2022-BLG-0371, and KMT-2022-BLG-1013, for which the light curves exhibit partially covered short-term cen…
