OGLE-2012-BLG-0563: Relative Proper Motion Constraint from Keck Follow-up Finds the Correct Lens

Abstract We present Keck/NIRC2 adaptive optics imaging results of planetary microlensing event OGLE-2012-BLG-0563. We find that the OGLE-2012-BLG-0563L planetary system consists of a 1.12 ± 0.09 M Jup planet orbiting a 0.81 ± 0.04 M ⊙ host star at a distance of 5.49 ± 0.56 kpc fr...

Gaia Science Alerts microlensing events with mass estimates verifiable in Gaia Data Release 4

Gaia Science Alerts provide an all-sky stream of photometric transients, including events consistent with gravitational microlensing. For such events, forthcoming epoch astrometry from the Gaia mission offers the possibility of testing photometric lens mass predictions. While mic...
