OGLE-2017-BLG-1522: A giant planet around a brown dwarf located in the Galactic bulge
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 despite the relatively short event timescale ...
OGLE-2017-BLG-0537: A Microlensing Event with a Resolvable Lens in ≲5 years from High-resolution Follow-up Observations
© 2018. The American Astronomical Society. All rights reserved. We present an analysis of the binary-lens microlensing event OGLE-2017-BLG-0537. The light curve of the event exhibits two strong caustic-crossing spikes among ...
OGLE-2017-BLG-0039: Microlensing Event with Light from a Lens Identified from Mass Measurement
© 2018. The American Astronomical Society. All rights reserved. We present an analysis of the caustic-crossing binary microlensing event OGLE-2017-BLG-0039. Thanks to the very long duration of the event, with a time scale ...
