Measurement of Dependence of Microlensing Planet Frequency on The Host Star Mass and Galactocentric Distance by using a Galactic Model
Kansuke Nunota, Naoki Koshimoto, Daisuke Suzuki +6
We measure the dependence of planet frequency on host star mass, , and distance from the Galactic center, , using a sample of planets discovered by gravitatio…
Precise mass measurement of OGLE-2013-BLG-0132/MOA-2013-BLG-148: a Saturn mass planet orbiting an M-dwarf
Natalia E. Rektsini, Virginie Batista, Clement Ranc +10
We revisit the planetary microlensing event OGLE-2013-BLG-0132/MOA-2013-BLG-148 using Keck adaptive optics imaging in 2013 with NIRC2 and in 2020, 7.4 years after the event, with O…
Confirmation of Color Dependent Centroid Shift Measured After 1.8 years with HST
Aparna Bhattacharya, David Bennett, Jean Philippe Beaulieu +10
We measured precise masses of the host and planet in OGLE-2003-BLG-235 system, when the lens and source were resolving, with 2018 Keck high resolution images. This measurement is i…
AIROPA III: Testing Simulated and On-Sky Data
Paolo Turri, Jessica R. Lu, Gunther Witzel +6
Adaptive optics images from the W. M. Keck Observatory have delivered numerous influential scientific results, including detection of multi-system asteroids, the supermassive black…
