The GRAVITY young stellar object survey: XI. Imaging the hot gas emission around the Herbig Ae star HD 58647
Y. -I. Bouarour, R. Garcia Lopez, J. Sanchez-Bermudez +45
We aim to investigate the origin of the HI Br emission in young stars by using GRAVITY to image the innermost region of circumstellar disks, where important physical processes s…
First VLTI/GRAVITY Observations of HIP 65426 b: Evidence for a Low or Moderate Orbital Eccentricity
S. Blunt, W. O. Balmer, J. J. Wang +95
Giant exoplanets have been directly imaged over orders of magnitude of orbital separations, prompting theoretical and observational investigations of their formation pathways. In t…
Revisiting the atmosphere of the exoplanet 51 Eridani b with VLT/SPHERE
S. B. Brown-Sevilla, A. -L. Maire, P. Mollière +27
[Full abstract in the paper] We aim to better constrain the atmospheric properties of the directly imaged exoplanet 51~Eri~b by using a retrieval approach on higher signal-to-noise…
Direct discovery of the inner exoplanet in the HD206893 system. Evidence for deuterium burning in a planetary-mass companion
S. Hinkley, S. Lacour, G. -D. Marleau +110
Long term precise radial velocity (RV) monitoring of the nearby star HD206893, as well as anomalies in the system proper motion, have suggested the presence of an additional, inner…
Constraining masses and separations of unseen companions to five accelerating nearby stars
D. Mesa, M. Bonavita, S. Benatti +39
Aims. This work aims at constraining the masses and separations of potential substellar companions to five accelerating stars (HIP 1481, HIP 88399, HIP 96334, HIP 30314 and HIP 116…
High-contrast, high-angular resolution view of the GJ 367 exoplanet system
Wolfgang Brandner, Per Calissendorff, Neige Frankel +1
We search for additional companions in the GJ 367 exoplanet system, and aim at better constraining its age and evolutionary status. We analyse high contrast direct imaging observat…
