Systematic KMTNet Planetary Anomaly Search. VII. Complete Sample of q < 10−4 Planets from the First 4 yr Survey

open access: yesThe Astronomical Journal, 2023
We present the analysis of seven microlensing planetary events with planet/host mass ratios q < 10 ^−4 : KMT-2017-BLG-1194, KMT-2017-BLG-0428, KMT-2019-BLG-1806, KMT-2017-BLG-1003, KMT-2019-BLG-1367, OGLE-2017-BLG-1806, and KMT-2016-BLG-1105.

KMT-2019-BLG-1715: Planetary Microlensing Event with Three Lens Masses and Two Source Stars [PDF]

open access: yesAstronomical Journal, 2021
We investigate the gravitational microlensing event KMT-2019-BLG-1715, the light curve of which shows two short-term anomalies from a caustic-crossing binary-lensing light curve: one with a large deviation and the other with a small deviation.

Mass Production of 2021 KMTNet Microlensing Planets. III. Analysis of Three Giant Planets

open access: yesThe Astronomical Journal, 2022
We present the analysis of three more planets from the KMTNet 2021 microlensing season. KMT-2021-BLG-0119Lb is a ∼6 M _Jup planet orbiting an early M dwarf or a K dwarf, KMT-2021-BLG-0192Lb is a ∼2 M _Nep planet orbiting an M dwarf, and KMT-2021-BLG ...

KMT-2019-BLG-0371 and the Limits of Bayesian Analysis [PDF]

open access: yes, 2021
We show that the perturbation at the peak of the light curve of microlensing event KMT-2019-BLG-0371 is explained by a model with a mass ratio between the host star and planet of q ∼ 0.08.

KMT-2017-BLG-2820 and the Nature of the Free-floating Planet Population [PDF]

open access: yesAstronomical Journal, 2020
We report a new free-floating planet (FFP) candidate, KMT-2017-BLG-2820, with Einstein radius θ E ≃ 6 μas, lens-source relative proper motion μ rel ≃ 8 mas yr−1, and Einstein timescale t E = 6.5 hr. It is the third FFP candidate found in an ongoing study

Shortest Microlensing Event with a Bound Planet: KMT-2016-BLG-2605 [PDF]

open access: yesAstronomical Journal, 2021
With a planet–host mass ratio q = 0.012 ± 0.001, KMT-2016-BLG-2605 has the shortest Einstein timescale, t E = 3.41 ± 0.13 days, of any planetary microlensing event to date.

Mass Production of 2021 KMTNet Microlensing Planets II

open access: yesThe Astronomical Journal, 2023
We continue our program of publishing all planets (and possible planets) found by eye in 2021 Korea Microlensing Telescope Network (KMTNet) online data. We present four planets (KMT-2021-BLG-0712Lb, KMT-2021-BLG-0909Lb, KMT-2021-BLG-2478Lb, and KMT-2021 ...

KMT-2019-BLG-2073: Fourth Free-floating Planet Candidate with θ E < 10 μas [PDF]

open access: yes, 2020
We analyze the very short Einstein timescale (t E ≃ 7 hr) event KMT-2019-BLG-2073. Making use of the pronounced finite-source effects generated by the clump giant source, we measure the Einstein radius θ E ≃ 4.8 μas and so infer a mass M=59M⊕(πrel/16μas)−
