A Multi-Parameter Degeneracy in Microlensing Events with Extreme Finite Source Effects
Samson A. Johnson, Matthew T. Penny, B. Scott Gaudi
For microlenses with sufficiently low mass, the angular radius of the source star can be much larger than the angular Einstein ring radius of the lens. For such extreme finite sour…
Systematic KMTNet Planetary Anomaly Search, Paper I: OGLE-2019-BLG-1053Lb, A Buried Terrestrial Planet
Weicheng Zang, Kyu-Ha Hwang, Andrzej Udalski +69
In order to exhume the buried signatures of "missing planetary caustics" in the KMTNet data, we conducted a systematic anomaly search to the residuals from point-source point-lens…
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…
