MOA-2020-BLG-108Lb: A Giant Planet Beyond the Snow Line of a Low-Mass Lens Near the Lower Boundary of the Mass-Ratio Desert

Yuki K. Satoh, David P. Bennett, Takahiro Sumi +21

We present an analysis of the microlensing event MOA-2020-BLG-108, which was discovered in June 2020 by the MOA collaboration toward the Galactic bulge. The observed light curve sh…

Historic microlensing events in the euclid Galactic Bulge Survey

V. Bozza, L. Salmeri, P. Rota +47

Microlensing campaigns have a long history of observations covering the Galactic bulge, where thousands of detections have been obtained, including many exoplanetary systems. The E…

OGLE-2015-BLG-1609Lb: Sub-jovian planet orbiting a low-mass stellar or brown dwarf host

M. J. Mróz, R. Poleski, A. Udalski +70

We present a comprehensive analysis of a planetary microlensing event OGLE-2015-BLG-1609. The planetary anomaly was detected by two survey telescopes, OGLE and MOA. Each of these s…

Dark lens candidates from Gaia Data Release 3

K. Kruszyńska, Ł. Wyrzykowski, K. A. Rybicki +48

Gravitational microlensing is a phenomenon that allows us to observe dark remnants of stellar evolution even if they no longer emit electromagnetic radiation. In particular, it can…

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…
