Systematic KMTNet Planetary Anomaly Search. XIII. Complete Sample of 2021 Prime Field Planets

In-Gu Shin, Jennifer C. Yee, Weicheng Zang, Cheongho Han et autres

Abstract The Systematic KMTNet Planetary Anomaly Search series was conducted using the KMTNet data archived from 2016–2019. From this first phase of the series, we reported a total of 50 planetary systems hidden in the data archive, which represent about 35% of …

Mass Production of 2023 KMTNet Microlensing Planets. III. Three Planets from the Subprime Field

Hongyu Li, Zhixing Li, Weicheng Zang, Yoon-Hyun Ryu et autres

Abstract To complete the analysis of the 2023 KMTNet subprime-field microlensing planetary events identified by its AlertFinder system, we present the analysis of six events, KMT-2023-BLG-(1810, 0084, 1118, 0584, 1697, 2218). We find that the first three events are securely confirmed as …

Four Cold Giant Planets Discovered by High-cadence Microlensing Surveys

Cheongho Han, Chung‐Uk Lee, A. Udalski, Ian A. Bond et autres

Abstract We report the discovery of four cold giant planets identified through the analysis of microlensing events detected by high-cadence surveys: OGLE-2016-BLG-0261, KMT-2025-BLG-0026, KMT-2025-BLG-0030, and KMT-2025-BLG-2272. The planetary signals appear as short-duration anomalies in the light curves and are well described by …

Mass Production of 2023 KMTNet Microlensing Planets. II: Two Planets and A Brown Dwarf

Zhixing Li, Hongyu Li, Weicheng Zang, Yoon-Hyun Ryu et autres

To expand the homogeneous microlensing planetary sample of the Korea Microlensing Telescope Network (KMTNet), we investigate six planetary candidates identified by the AnomalyFinder search in the 2023 prime-field data, namely KMT-2023-BLG-1592, OGLE-2023-BLG-0766, KMT-2023-BLG-0332, KMT-2023-BLG-0486, KMT-2023-BLG-0792, and OGLE-2023-BLG-1043. Light-curve modeling indicates that the …

Three Saturn-mass Microlensing Planets Identified through Signals from Peripheral-caustic Perturbations

Cheongho Han, Chung-Uk Lee, Andrzej Udalski, I. Bond et autres

Abstract We present the discovery and analysis of three microlensing planets identified through brief positive anomalies on the wings of their light curves. The events, KMT-2021-BLG-0852, KMT-2024-BLG-2005, and KMT-2025-BLG-0481, were detected in high-cadence survey data from the KMTNet, OGLE, MOA, and PRIME …

KMT-2025-BLG-1616Lb: First Microlensing Bound Planet From DREAMS

Hongjing 弘靖 Yang 杨, Weicheng 伟呈 Zang 臧, Yoon-Hyun Ryu, Takahiro Sumi et autres

Abstract We present observations and analysis of the bound planetary microlensing event KMT-2025-BLG-1616. The planetary signal was captured by the Korea Microlensing Telescope Network and the Dark Energy Camera Rogue Earths and Mars Survey (DREAMS). DREAMS’s minute-cadence observations break the central/resonant degeneracy …

A Précis of the MOA-II Observations

Jasmine Anderson-Baldwin, Michele T. Bannister, Preeti Cowan, Nicholas J. Rattenbury et autres

Abstract The Microlensing Observations in Astrophysics (MOA) collaboration is an international research project that uses gravitational microlensing for the discovery of exoplanets. MOA was initiated in the late 1990s and primarily involves institutions from Japan and New Zealand. The collaboration’s observation site …

KMT-2022-BLG-1818Lb,c: A Cold Super-Jupiter with a Saturn Sibling

J. Zhang, Cheongho Han, Weicheng Zang, Youn Kil Jung et autres

Abstract We present the discovery and analysis of the sixth microlensing two-planet system, KMT-2022-BLG-1818Lb,c, detected by a follow-up program targeting high-magnification events. The second planet was identified from implausible physical parameters for the models with a single planet. Both planets are subject …
