OGLE-2019-BLG-0960Lb: The Smallest Microlensing Planet

Jennifer C. Yee, Weicheng Zang, Andrzej Udalski +80

We report the analysis of OGLE-2019-BLG-0960, which contains the smallest mass-ratio microlensing planet found to date (q = 1.2--1.6 x 10^{-5} at 1-sigma). Although there is substa…

MOA-2007-BLG-197: Exploring the brown dwarf desert

C. Ranc, A. Cassan, M. D. Albrow +48

We present the analysis of MOA-2007-BLG-197Lb, the first brown dwarf companion to a Sun-like star detected through gravitational microlensing. The event was alerted and followed-up…
