OGLE-2014-BLG-0319: A Sub-Jupiter-Mass Planetary Event Encountered Degeneracy with Different Mass Ratios and Lens-Source Relative Proper Motions

Shota Miyazaki, Daisuke Suzuki, Andrzej Udalski +36

We report the discovery of a sub-Jovian-mass planet, OGLE-2014-BLG-0319Lb. The characteristics of this planet will be added into a future extended statistical analysis of the Micro…

KMT-2021-BLG-0912Lb: A microlensing super Earth around a K-type star

Cheongho Han, Ian A. Bond, Jennifer C. Yee +55

The light curve of the microlensing event KMT-2021-BLG-0912 exhibits a very short anomaly relative to a single-lens single-source form. We investigate the light curve for the purpo…

KMT-2021-BLG-0322: Severe degeneracy between triple-lens and higher-order binary-lens interpretations

Cheongho Han, Andrew Gould, Yuki Hirao +46

We investigate the microlensing event KMT-2021-BLG-0322, for which the light curve exhibits three distinctive sets of caustic-crossing features. It is found that the overall featur…

New Giant Planet beyond the Snow Line for an Extended MOA Exoplanet Microlens Sample

Clément Ranc, David P. Bennett, Richard K. Barry +28

Characterizing a planet detected by microlensing is hard if the planetary signal is weak or the lens-source relative trajectory is far from caustics. However, statistical analyses…

Systematic KMTNet Planetary Anomaly Search, Paper II: Six New Mass-ratio Planets

Kyu-Ha Hwang, Weicheng Zang, Andrew Gould +62

We apply the automated AnomalyFinder algorithm of Paper I (Zang et al. 2021b) to 2018-2019 light curves from the covered by the six KMTNet prime fields, wi…

MOA-2006-BLG-074: recognizing xallarap contaminants in planetary microlensing

P. Rota, Y. Hirao, V. Bozza +23

MOA-2006-BLG-074 was selected as one of the most promising planetary candidates in a retrospective analysis of the MOA collaboration: its asymmetric high-magnification peak can be…
