OGLE-2017-BLG-1049: Another giant planet microlensing event

Yun Hak Kim, Sun-Ju Chung, A. Udalski +55

We report a giant exoplanet discovery in the microlensing event OGLE-2017-BLG-1049, which is a planet-host star mass ratio of and has a caustic crossin…

A Giant Planet Candidate Transiting a White Dwarf

Andrew Vanderburg, Saul A. Rappaport, Siyi Xu +61

Astronomers have discovered thousands of planets outside the solar system, most of which orbit stars that will eventually evolve into red giants and then into white dwarfs. During…

MOA-2007-BLG-400 A Super-Jupiter Mass Planet Orbiting a Galactic BulgeK-dwarf Revealed by Keck Adaptive Optics Imaging

Aparna Bhattacharya, David P. Bennett, Jean P. Beaulieu +11

We present Keck/NIRC2 adaptive optics imaging of planetary microlensing event MOA-2007-BLG-400 that resolves the lens star system from the source. We find that the MOA-2007-BLG-400…

The TESS-Keck Survey II: An Ultra-Short Period Rocky Planet and its Siblings Transiting the Galactic Thick-Disk Star TOI-561

Lauren M. Weiss, Fei Dai, Daniel Huber +61

We report the discovery of TOI-561, a multi-planet system in the galactic thick disk that contains a rocky, ultra-short period planet (USP). This bright () star hosts three…
