Four Giant Planets from 2024 KMTNet Microlensing Campaign
Cheongho Han, Andrzej Udalski, Ian A. Bond +56
In this work, we present analyses of four newly discovered planetary microlensing events from the 2024 KMTNet survey season: KMT-2024-BLG-0176, KMT-2024-BLG-0349, KMT-2024-BLG-1870…
A Comprehensive Analysis of Three Microlensing Planet Candidates with the Planet/Binary Degeneracy
Jiyuan Zhang, Weicheng Zang, Yoon-Hyun Ryu +65
We present observations and analyses of three high-magnification microlensing events: KMT-2022-BLG-0954, KMT-2024-BLG-0697, and MOA-2024-BLG-018. All three exhibit the "Planet/Bina…
Binary-lens Microlensing Degeneracy: Impact on Planetary Sensitivity and Mass-ratio Function
Yuxin Shang, Hongjing Yang, Jiyuan Zhang +5
Gravitational microlensing is a unique method for discovering cold planets across a broad mass range. Reliable statistics of the microlensing planets require accurate sensitivity e…
KMT-2022-BLG-1818Lb,c: A Cold Super-Jupiter with a Saturn Sibling
Hongyu Li, Jiyuan Zhang, Cheongho Han +72
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. Both…
Microlensing events indicate that super-Earth exoplanets are common in Jupiter-like orbits
Weicheng Zang, Youn Kil Jung, Jennifer C. Yee +65
Exoplanets classified as super-Earths are commonly observed on short period orbits, close to their host stars, but their abundance on wider orbits is poorly constrained. Gravitatio…
Systematic KMTNet Planetary Anomaly Search. XII. Complete Sample of 2017 Subprime Field Planets
Yuqian Gui, Weicheng Zang, Ruocheng Zhai +39
We report the analysis of four unambiguous planets and one possible planet from the subprime fields () of the 2017 Korea Microlensing Telescope Network (KMTN…
Systematic Search for FFPs in KMTNet Full-Frame Images. I. Photometry Pipeline
Qiyue Qian, Hongjing Yang, Weicheng Zang +22
To exhume the buried signatures of free-floating planets (FFPs) with small angular Einstein radius , we build a new full-frame difference image pipeline for the Korean M…
