Image-constrained Modeling with Hubble and Keck Images Reveals that OGLE-2012-BLG-0563Lb is a Jupiter-mass Planet Orbiting a K Dwarf

Abstract We present high-angular-resolution imaging from the Hubble Space Telescope combined with adaptive optics imaging results from the Keck-II telescope to determine the mass of the OGLE-2012-BLG-0563L host star and planet to be M host = 0.801 ± 0.033 M ⊙ and M planet = 1.116...

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...
