HD 143811 AB b: A Directly Imaged Planet Orbiting a Spectroscopic Binary in Sco-Cen

Nathalie K. Jones, Jason J. Wang, Eric L. Nielsen +51

We present confirmation of HD 143811 AB b, a substellar companion to spectroscopic binary HD 143811 AB through direct imaging with the Gemini Planet Imager (GPI) and Keck NIRC2. HD…

The Gemini Planet Imager Exoplanet Survey: Dynamical Mass of the Exoplanet beta Pictoris b from Combined Direct Imaging and Astrometry

Eric L. Nielsen, Robert J. De Rosa, Jason J. Wang +51

We present new observations of the planet beta Pictoris b from 2018 with GPI, the first GPI observations following conjunction. Based on these new measurements, we perform a joint…

An Exo-Kuiper Belt and An Extended Halo around HD 191089 in Scattered Light

Bin Ren, Élodie Choquet, Marshall D. Perrin +70

We have obtained Hubble Space Telescope STIS and NICMOS, and Gemini/GPI scattered light images of the HD 191089 debris disk. We identify two spatial components: a ring resembling K…

Constraints on HD113337 fundamental parameters and planetary system. Combining long-base visible interferometry, disk imaging and high-contrast imaging

S. Borgniet, K. Perraut, K. Su +13

HD113337 is a Main-Sequence F6V field star more massive than the Sun, hosting one (possibly two) radial velocity (RV) giant planet(s) and a cold debris disk (marked by an infrared…

Further Evidence of the Planetary Nature of HD 95086 b from Gemini/NICI H-band Data

T. Meshkat, V. Bailey, J. Rameau +8

We present our analysis of the Gemini/NICI H-band data of HD 95086, following the discovery of the planet HD 95086 b in L'. The H-band data reach a contrast of 12.7 mag relative to…
