Mass Production of 2021 KMTNet Microlensing Planets III: Analysis of Three Giant Planets
In-Gu Shin, Jennifer C. Yee, Andrew Gould +45
We present the analysis of three more planets from the KMTNet 2021 microlensing season. KMT-2021-BLG-0119Lb is a planet orbiting an early M-dwarf or a K-dwar…
The Astrometric Animation of Water Masers towards the Mira Variable BX Cam
Shuangjing Xu, Hiroshi Imai, Youngjoo Yun +20
We report VLBI monitoring observations of the 22 GHz water (HO) masers around the Mira variable BX Cam, which were carried out as a part of the EAVN Synthesis of Stellar Mase…
Systematic KMTNet Planetary Anomaly Search, Paper VII: Complete Sample of Planets from the First Four-Year Survey
