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…

Characterization of the Host Binary of the Directly Imaged Exoplanet HD 143811 AB b

Anne E. Peck, William Roberson, Eric L. Nielsen +50

HD~143811~AB is the host star to the directly imaged planet HD~143811~AB~b, which was recently discovered using data from the Gemini Planet Imager and Keck NIRC2. A member of the S…

The mass of Beta Pictoris c from Beta Pictoris b orbital motion

S. Lacour, J. J. Wang, L. Rodet +96

We aim to demonstrate that the presence and mass of an exoplanet can now be effectively derived from the astrometry of another exoplanet. We combined previous astrometry of Pic…

GRAVITY K-band spectroscopy of HD 206893 B: brown dwarf or exoplanet

J. Kammerer, S. Lacour, T. Stolker +94

We aim to reveal the nature of the reddest known substellar companion HD 206893 B by studying its near-infrared colors and spectral morphology and by investigating its orbital moti…

Constraining the Nature of the PDS 70 Protoplanets with VLTI/GRAVITY

J. J. Wang, A. Vigan, S. Lacour +101

We present K-band interferometric observations of the PDS 70 protoplanets along with their host star using VLTI/GRAVITY. We obtained K-band spectra and 100 as precision astromet…

The ExoGRAVITY project: using single mode interferometry to characterize exoplanets

S. Lacour, J. J. Wang, M. Nowak +89

Combining adaptive optics and interferometric observations results in a considerable contrast gain compared to single-telescope, extreme AO systems. Taking advantage of this, the E…
