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…

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…

Precision measurement of a brown dwarf mass in a binary system in the microlensing event OGLE-2019-BLG-0033/MOA-2019-BLG-035

A. Herald, A. Udalski, V. Bozza +89

Context. Brown dwarfs are poorly understood transition objects between stars and planets, with several competing mechanisms having been proposed for their formation. Mass measureme…

Systematic KMTNet Planetary Anomaly Search. V. Complete Sample of 2018 Prime-Field

Andrew Gould, Cheongho Han, Weicheng Zang +65

We complete the analysis of all 2018 prime-field microlensing planets identified by the KMTNet AnomalyFinder. Among the 10 previously unpublished events with clear planetary soluti…

MOA-2020-BLG-135Lb: A New Neptune-class Planet for the Extended MOA-II Exoplanet Microlens Statistical Analysis

Stela Ishitani Silva, Clément Ranc, David P. Bennett +33

We report the light-curve analysis for the event MOA-2020-BLG-135, which leads to the discovery of a new Neptune-class planet, MOA-2020-BLG-135Lb. With a derived mass ratio of $q=1…

KMT-2021-BLG-1077L: The fifth confirmed multiplanetary system detected by microlensing

Cheongho Han, Andrew Gould, Ian A. Bond +45

The high-magnification microlensing event KMT-2021-BLG-1077 exhibits a subtle and complex anomaly pattern in the region around the peak. We analyze the lensing light curve of the e…
