Multiwavelength properties of Miras

Patryk Iwanek, Szymon Kozłowski, Mariusz Gromadzki +12

We comprehensively study the variability of Miras in the Large Magellanic Cloud (LMC) by simultaneous analysing light curves in 14 bands in the range of 0.524 microns. We model…

Systematic KMTNet Planetary Anomaly Search, Paper II: Six New Mass-ratio Planets

Kyu-Ha Hwang, Weicheng Zang, Andrew Gould +62

We apply the automated AnomalyFinder algorithm of Paper I (Zang et al. 2021b) to 2018-2019 light curves from the covered by the six KMTNet prime fields, wi…

OGLE-2018-BLG-1185b : A Low-Mass Microlensing Planet Orbiting a Low-Mass Dwarf

Iona Kondo, Jennifer C. Yee, David P. Bennett +94

We report the analysis of planetary microlensing event OGLE-2018-BLG-1185, which was observed by a large number of ground-based telescopes and by the Space Telescope. The…

Three microlensing planets with no caustic-crossing features

Cheongho Han, Andrzej Udalski, Doeon Kim +31

We search for microlensing planets with signals exhibiting no caustic-crossing features, considering the possibility that such signals may be missed due to their weak and featurele…

Wide-orbit exoplanets are common. Analysis of nearly 20 years of OGLE microlensing survey data

R. Poleski, J. Skowron, P. Mróz +8

We use nearly 20 years of photometry obtained by the OGLE survey to measure the occurrence rate of wide-orbit (or ice giant) microlensing planets, i.e., with separations from ~5 AU…

KMT-2018-BLG-1025Lb: microlensing super-Earth planet orbiting a low-mass star

Cheongho Han, Andrzej Udalski, Chung-Uk Lee +32

We aim to find missing microlensing planets hidden in the unanalyzed lensing events of previous survey data. For this purpose, we conduct a systematic inspection of high-magnificat…
