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-ing the Magellanic System: Optical Reddening Maps of the Large and Small Magellanic Cloud from Red Clump Stars

D. M. Skowron, J. Skowron, A. Udalski +12

We present the most extensive and detailed reddening maps of the Magellanic Clouds (MCs) derived from the color properties of Red Clump (RC) stars. The analysis is based on the dee…

A Gas Giant Planet in the OGLE-2006-BLG-284L Stellar Binary System

David P. Bennett, Andrzej Udalski, Ian A. Bond +32

We present the analysis of microlensing event OGLE-2006-BLG-284, which has a lens system that consists of two stars and a gas giant planet with a mass ratio of $q_p = (1.26\pm 0.19…
