First Direct Identification of a Multi-Star Microlens System Hosting a Planet
Sean K. Terry, David P. Bennett, Jean-Philippe Beaulieu +11
Nearly 25 years have passed since gravitational microlensing delivered its first exoplanet discoveries. The relative proper motion between lens and source systems allows them to be…

We present an analysis that incorporates high-resolution Keck adaptive optics (AO) imaging into microlensing light-curve modeling for the planetary microlensing event OGLE-2014-BLG…
Constraints on the possible atmospheres on TRAPPIST-1 b: insights from 3D climate modeling
Alice Maurel, Martin Turbet, Elsa Ducrot +13
JWST observations of the secondary eclipse of TRAPPIST-1 b at 12.8 and 15 microns revealed a very bright dayside. These measurements are consistent with an absence of atmosphere. P…
TASSIE: a TASmanian Search for Inclined Exoplanets
T. Plunkett, A. A. Cole, J. P. Beaulieu +5
We present the first results of a pilot 'TASmanian Search for Inclined Exoplanets' (TASSIE) program. This includes observations and analysis of five short-period exoplanet candidat…
MOA-2010-BLG-328: Keck and HST Expose the Limits of Occams Razor in Microlensing
Aikaterini Vandorou, David P. Bennett, Jean-Philippe Beaulieu +7
We present high resolution follow-up data of the planetary microlensing event MOA-2010-BLG-328, using Keck and the Hubble. Keck data, taken 8 years after the event, reveal a strong…
OGLE-2014-BLG-1760: A Jupiter-Sun analogue residing in the Galactic Bulge
Natalia E. Rektsini, Clement Ranc, Naoki Koshimoto +11
We present the analysis of OGLE-2014-BLG-1760, a planetary system in the galactic bulge. We combine Keck Adaptive Optics follow-up observations in -band with re-reduced light cu…
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…
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…
ARES VI: Viability of one-dimensional retrieval models for transmission spectroscopy characterization of exo-atmospheres in the era of JWST and Ariel
Adam Yassin Jaziri, William Pluriel, Andrea Bocchieri +10
Observed exoplanet transit spectra are usually retrieved using 1D models to determine atmospheric composition while planetary atmospheres are 3D. With the JWST and future space tel…
OGLE-2016-BLG-1195Lb: A Sub-Neptune Beyond the Snow Line of an M-dwarf Confirmed by Keck AO
Aikaterini Vandorou, Lisa Dang, David P. Bennett +12
We present the analysis of high resolution follow-up observations of OGLE-2016-BLG-1195 using Laser Guide Star Adaptive Optics with Keck, seven years after the event's peak. We res…
