OGLE-2018-BLG-0584 and KMT-2018-BLG-2119: two microlensing events with two lens masses and two source stars
Cheongho Han, Andrzej Udalski, Youn Kil Jung +34
We conduct a systematic investigation of the microlensing data collected during the previous observation seasons for the purpose of reanalyzing anomalous lensing events with no sug…
A three-dimensional map of the Milky Way using 66,000 Mira variable stars
Patryk Iwanek, Radosław Poleski, Szymon Kozłowski +13
We study the three-dimensional structure of the Milky Way using 65,981 Mira variable stars discovered by the Optical Gravitational Lensing Experiment (OGLE) survey. The spatial dis…
New Short-Period Delta Scuti Stars in OGLE-IV Fields toward the Galactic Bulge
P. Pietrukowicz, M. Ratajczak, I. Soszynski +12
We report the classification of 24 puzzling short-period variable stars located in OGLE-IV Galactic bulge fields. The stars are low-amplitude (<0.05 mag) multi-periodic objects wit…
Systematic KMTNet Planetary Anomaly Search, Paper VII: Complete Sample of Planets from the First Four-Year Survey
Weicheng Zang, Youn Kil Jung, Hongjing Yang +36
We present the analysis of seven microlensing planetary events with planet/host mass ratios : KMT-2017-BLG-1194, KMT-2017-BLG-0428, KMT-2019-BLG-1806, KMT-2017-BLG-100…
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…
OGLE-2019-BLG-0362Lb: A super-Jovian-mass planet around a low-mass star
Sun-Ju Chung, Jennifer C. Yee, Andrej Udalski +28
We present the analysis of a planetary microlensing event OGLE-2019-BLG-0362 with a short-duration anomaly near the peak of the light curve, which is caused…
