New Self-lensing Models of the Small Magellanic Cloud: Can Gravitational Microlensing Detect Extragalactic Exoplanets?

Przemek Mroz, Radoslaw Poleski

We use three-dimensional distributions of classical Cepheids and RR~Lyrae stars in the Small Magellanic Cloud (SMC) to model the stellar density distribution of a young and old ste…

A Neptune-mass Free-floating Planet Candidate Discovered by Microlensing Surveys

Przemek Mroz, Y. -H. Ryu, J. Skowron +26

Current microlensing surveys are sensitive to free-floating planets down to Earth-mass objects. All published microlensing events attributed to unbound planets were identified base…

OGLE-2017-BLG-0173Lb: Low Mass-Ratio Planet in a "Hollywood" Microlensing Event

K. -H. Hwang, A. Udalski, Y. Shvartzvald +34

We present microlensing planet OGLE-2017-BLG-0173Lb, with planet-host mass ratio either or , the lowest or among the lowest e…

Ground-based parallax confirmed by Spitzer: binary microlensing event MOA-2015-BLG-020

Tianshu Wang, Wei Zhu, Shude Mao +83

We present the analysis of the binary gravitational microlensing event MOA-2015-BLG-020. The event has a fairly long timescale (about 63 days) and thus the light curve deviates sig…

No large population of unbound or wide-orbit Jupiter-mass planets

Przemek Mroz, Andrzej Udalski, Jan Skowron +9

Gravitational microlensing is the only method capable of exploring the entire population of free-floating planets down to Mars-mass objects, because the microlensing signal does no…

OGLE-2016-BLG-0693LB: Probing the Brown Dwarf Desert with Microlensing

Y. -H. Ryu, A. Udalski, J. C. Yee +25

We present an analysis of microlensing event OGLE-2016-BLG-0693, based on the survey-only microlensing observations by the OGLE and KMTNet groups. In order to analyze the light cur…
