OGLE-2017-BLG-1049: Another giant planet microlensing event
Yun Hak Kim, Sun-Ju Chung, A. Udalski +55
We report a giant exoplanet discovery in the microlensing event OGLE-2017-BLG-1049, which is a planet-host star mass ratio of and has a caustic crossin…
A terrestrial-mass rogue planet candidate detected in the shortest-timescale microlensing event
P. Mroz, R. Poleski, A. Gould +27
Some low-mass planets are expected to be ejected from their parent planetary systems during early stages of planetary system formation. According to planet-formation theories, such…
KMT-2017-BLG-2820 and the Nature of the Free-Floating Planet Population
Yoon-Hyun Ryu, Przemek Mróz, Andrew Gould +28
We report a new free-floating planet (FFP) candidate, KMT-2017-BLG-2820, with Einstein radius $θ_\e\simeq 6\,\muas$, lens-source relative proper motion $μ_\rel \simeq 8\,\masyr$, a…
OGLE-2018-BLG-0799Lb: a Planet with Spitzer Parallax
Weicheng Zang, Yossi Shvartzvald, Andrzej Udalski +73
We report the discovery and analysis of a planet in the microlensing event OGLE-2018-BLG-0799. The planetary signal was observed by several ground-based telescopes, and the planet-…
Four Microlensing Planets with Faint-source Stars Identified in the 2016 and 2017 Season Data
Cheongho Han, Andrzej Udalski, Doeon Kim +32
Microlensing planets occurring on faint source stars can escape detection due to their weak signals. Occasionally, detections of such planets are not reported due to the difficulty…
KMT-2018-BLG-0748Lb: Sub-Saturn Microlensing Planet Orbiting an Ultracool Host
Cheongho Han, In-Gu Shin, Youn Kil Jung +18
We announce the discovery of a microlensing planetary system, in which a sub-Saturn planet is orbiting an ultracool dwarf host. We detect the planetary system by analyzing the shor…
KMT-2019-BLG-2073: Fourth Free-Floating-Planet Candidate with $θ_\rm E < 10 \rmμas$
Hyoun-Woo Kim, Kyu-Ha Hwang, Andrew Gould +17
We analyze the very short Einstein timescale ($t_\rm E \simeq 7\,{\rm hr}$) event KMT-2019-BLG-2073. Making use of the pronounced finite-source effects generated by the clump-giant…
OGLE-2018-BLG-1269Lb: A Jovian Planet With A Bright, Host
Youn Kil Jung, Andrew Gould, Andrzej Udalski +54
We report the discovery of a planet in the microlensing event OGLE-2018-BLG-1269, with planet-host mass ratio , i.e., times smaller than the Jupiter/Su…
OGLE-2017-BLG-0406: Microlens Parallax Reveals Saturn-mass Planet orbiting M-dwarf Host in the Inner Galactic Disk
Yuki Hirao, David P. Bennett, Yoon-Hyun Ryu +93
We report the discovery and analysis of the planetary microlensing event OGLE-2017-BLG-0406, which was observed both from the ground and by the satellite in a solar…
KMT-2019-BLG-1339L: an M Dwarf with a Giant Planet or a Companion Near the Planet/Brown Dwarf Boundary
Cheongho Han, Doeon Kim, Andrzej Udalski +31
We analyze KMT-2019-BLG-1339, a microlensing event with an obvious but incompletely resolved brief anomaly feature around the peak of the light curve. Although the origin of the an…
A free-floating or wide-orbit planet in the microlensing event OGLE-2019-BLG-0551
P. Mroz, R. Poleski, C. Han +30
High-cadence observations of the Galactic bulge by the microlensing surveys led to the discovery of a handful of extremely short-timescale microlensing events that can be attribute…
One Planet or Two Planets? The Ultra-sensitive Extreme-magnification Microlensing Event KMT-2019-BLG-1953
Cheongho Han, Doeon Kim, Youn Kil Jung +48
We present the analysis of a very high-magnification () microlensing event KMT-2019-BLG-1953. A single-lens single-source (1L1S) model appears to approximately delineate…
