OGLE-2013-BLG-0911Lb: A Secondary on the Brown-Dwarf Planet Boundary around an M-dwarf

Shota Miyazaki, Takahiro Sumi, David P. Bennett +92

We present the analysis of the binary-lens microlensing event OGLE-2013-BLG-0911. The best-fit solutions indicate the binary mass ratio of q~0.03 which differs from that reported i…

KMT-2019-BLG-0842Lb: A Cold Planet Below the Uranus/Sun Mass Ratio

Youn Kil Jung, Andrzej Udalski, Weicheng Zang +59

We report the discovery of a cold planet with a very low planet/host mass ratio of , which is similar to the ratio of Uranus/Sun ($q=4.37 \times 10^…

Candidate Brown-dwarf Microlensing Events with Very Short Timescales and Small Angular Einstein Radii

Cheongho Han, Chung-Uk Lee, Andrzej Udalski +62

Short-timescale microlensing events are likely to be produced by substellar brown dwarfs (BDs), but it is difficult to securely identify BD lenses based on only event timescales $t…

OGLE-2018-BLG-1700L: Microlensing Planet in Binary Stellar System

Cheongho Han, Chung-Uk Lee, Andrzej Udalski +58

We report the discovery of a planet in a binary that was discovered from the analysis of the microlensing event OGLE-2018-BLG-1700. We identify the triple nature of the lens from t…

Keck Observations Confirm a Super-Jupiter Planet Orbiting M-dwarf OGLE-2005-BLG-071L

David P. Bennett, Aparna Bhattacharya, Jean-Philippe Beaulieu +10

We present adaptive optics imaging from the NIRC2 instrument on the Keck-2 telescope that resolves the exoplanet host (and lens) star as it separates from the brighter source star.…

Community Involvement in the WFIRST Exoplanet Microlensing Survey

David P. Bennett, Rachel Akeson, Thomas Barclay +22

WFIRST is NASA's first flagship mission with pre-defined core science programs to study dark energy and perform a statistical census of wide orbit exoplanets with a gravitational m…
