OGLE-2015-BLG-1609Lb: Sub-jovian planet orbiting a low-mass stellar or brown dwarf host

M. J. Mróz, R. Poleski, A. Udalski +70

We present a comprehensive analysis of a planetary microlensing event OGLE-2015-BLG-1609. The planetary anomaly was detected by two survey telescopes, OGLE and MOA. Each of these s…

Image-Constrained Modeling with Hubble and Keck Images Reveals that OGLE-2012-BLG-0563Lb is a Jupiter-Mass planet Orbiting a K Dwarf

David P. Bennett, Aparna Bhattacharya, Jean-Philippe Beaulieu +7

We present high angular resolution imaging from the {\sl Hubble Space Telescope} combined with adaptive optics imaging results from the {\sl Keck}-II telescope to determine the mas…

A Candidate High-Velocity Exoplanet System in the Galactic Bulge

Sean K. Terry, Jean-Philippe Beaulieu, David P. Bennett +11

We present an analysis of adaptive optics (AO) images from the Keck-I telescope of the microlensing event MOA-2011-BLG-262. The original discovery paper by Bennett et al. 2014 repo…

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…

Unveiling MOA-2007-BLG-192: An M Dwarf Hosting a Likely Super-Earth

Sean K. Terry, Jean-Philippe Beaulieu, David P. Bennett +15

We present an analysis of high angular resolution images of the microlensing target MOA-2007-BLG-192 using Keck adaptive optics and the Hubble Space Telescope. The planetary host s…

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…
