Thirty Circumbinary Disk Occultation Systems (KH 15D-like stars) from the OGLE Project

M. A. Urbanowicz, I. Soszyński, P. Pietrukowicz +14

We present a catalog of 30 stars that are candidates for KH 15D-like binary systems, in which the observed brightness variations are caused by a circumbinary dusty disk that period…

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

Hongyu Li, Zhixing Li, Weicheng Zang +56

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-(…

Candidate Microlensing Brown Dwarfs in Binary Lens Systems from the 2023--2025 Observing Seasons

Cheongho Han, Andrzej Udalski, Ian A. Bond +62

We present detailed light-curve analyses of ten binary-lens microlensing events observed during the 2023--2025 seasons and selected as candidates for hosting brown-dwarf companions…

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…
