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…

MOA-2020-BLG-208Lb: Cool Sub-Saturn Planet Within Predicted Desert

Greg Olmschenk, David P. Bennett, Ian A. Bond +74

We analyze the MOA-2020-BLG-208 gravitational microlensing event and present the discovery and characterization of a new planet, MOA-2020-BLG-208Lb, with an estimated sub-Saturn ma…

Brown-dwarf companions in microlensing binaries detected during the 2016--2018 seasons

Cheongho Han, Yoon-Hyun Ryu, In-Gu Shin +60

With the aim of finding microlensing binaries containing brown-dwarf (BD) companions, we investigate the microlensing survey data collected during the 2016--2018 seasons. For this…

KMT-2021-BLG-0171Lb and KMT-2021-BLG-1689Lb: Two Microlensing Planets in the KMTNet High-cadence Fields with Followup Observations

Hongjing Yang, Weicheng Zang, Andrew Gould +56

Follow-up observations of high-magnification gravitational microlensing events can fully exploit their intrinsic sensitivity to detect extrasolar planets, especially those with sma…

Four sub-Jovian-mass planets detected by high-cadence microlensing surveys

Cheongho Han, Doeon Kim, Andrew Gould +57

With the aim of finding short-term planetary signals, we investigated the data collected from the high-cadence microlensing surveys. From this investigation, we found four planetar…

MOA-2019-BLG-008Lb: a new microlensing detection of an object at the planet/brown dwarf boundary

E. Bachelet, Y. Tsapras, Andrew Gould +68

We report on the observations, analysis and interpretation of the microlensing event MOA-2019- BLG-008. The observed anomaly in the photometric light curve is best described throug…
