OGLE-2017-BLG-0537: Microlensing Event with a Resolvable Lens in years from High-resolution Follow-up Observations

Y. K. Jung, C. Han, A. Udalski +29

We present the analysis of the binary-lens microlensing event OGLE-2017-BLG-0537. The light curve of the event exhibits two strong caustic-crossing spikes among which the second ca…

Microlensing Parallax for OGLE-2017-BLG-0896 Reveals a Counter-Rotating Low-Mass Brown Dwarf

Yossi Shvartzvald, Jennifer C. Yee, Jan Skowron +63

The kinematics of isolated brown dwarfs in the Galaxy, beyond the solar neighborhood, is virtually unknown. Microlensing has the potential to probe this hidden population, as it ca…

Spitzer Opens New Path to Break Classic Degeneracy for Jupiter-Mass Microlensing Planet OGLE-2017-BLG-1140Lb

S. Calchi Novati, J. Skowron, Y. K. Jung +36

We analyze the combined Spitzer and ground-based data for OGLE-2017-BLG-1140 and show that the event was generated by a Jupiter-class planet orbiting…

OGLE-2017-BLG-1522: A giant planet around a brown dwarf located in the Galactic bulge

Y. K. Jung, A. Udalski, A. Gould +27

We report the discovery of a giant planet in the OGLE-2017-BLG-1522 microlensing event. The planetary perturbations were clearly identified by high-cadence survey experiments despi…

OGLE-2017-BLG-0373Lb: A Jovian Mass-Ratio Planet Exposes A New Accidental Microlensing Degeneracy

J. Skowron, Y. -H. Ryu, K. -H. Hwang +30

We report the discovery of microlensing planet OGLE-2017-BLG-0373Lb. We show that while the planet-host system has an unambiguous microlens topology, there are two geometries withi…
