Two Low Mass-Ratio Microlensing Planets and Two Types of Central-Resonant Degeneracy
Yuchen Tang, Weicheng Zang, Yoon-Hyun Ryu +39
We present observations and analysis of two low planet/host mass-ratio () microlensing planets discovered in high-magnification events. KMT-2025-BLG-0811Lb has $q \sim 4.5 \time…
KMT-2025-BLG-1616Lb: First Microlensing Bound Planet From DREAMS
Hongjing Yang, Weicheng Zang, Yoon-Hyun Ryu +60
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 (KMT…
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…
Systematic Reanalysis of KMTNet Microlensing Events, Paper II: Two New Planets in Giant-Source Events
Hongjing Yang, Jennifer C. Yee, Jiyuan Zhang +61
In this work, we continue to apply the updated KMTNet tender-love care (TLC) photometric pipeline to historical microlensing events. We apply the pipeline to a subsample of events…
