    • Blobs, spiral arms, and a possible planet around HD 169142 
      Gratton, R.; Ligi, R.; Sissa, E.; Desidera, S.; Mesa, D.; Bonnefoy, M.; Chauvin, G.; Cheetham, A.; Feldt, M.; Lagrange, Anne Marie; Langlois, M.; Meyer, M.; Vigan, A.; Boccaletti, A.; Janson, M.; Lazzoni, C.; Zurlo, A.; De Boer, J.; Henning, T.; D'Orazi, V.; Gluck, L.; Madec, F. (EDP Sciences, 2019)
      Context. Young planets are expected to cause cavities, spirals, and kinematic perturbations in protostellar disks that may be used to infer their presence. However, a clear detection of still-forming planets embedded within ...

(EDP Sciences, 2018)
      We report the discovery of a bright, brown dwarf companion to the star HIP 64892, imaged with VLT/SPHERE during the SHINE exoplanet survey. The host is a B9.5V member of the Lower-Centaurus-Crux subgroup of the Scorpius ...
    • Post-conjunction detection of β Pictoris b with VLT/SPHERE 
      Lagrange, Anne Marie; Boccaletti, A.; Langlois, M.; Chauvin, G.; Gratton, R.; Beust, H.; Desidera, S.; Milli, J.; Bonnefoy, M.; Cheetham, A.; Feldt, M.; Meyer, M.; Vigan, A.; Biller, B.; Bonavita, M.; Baudino, J. L.; Cantalloube, F.; Cudel, M.; Daemgen, S.; Delorme, P.; D'Orazi, (EDP Sciences, 2019)
      Context. With an orbital distance comparable to that of Saturn in the solar system, β Pictoris b is the closest (semi-major axis ≃ 9 au) exoplanet that has been imaged to orbit a star. Thus it offers unique opportunities ...
    • Searching for the near-infrared counterpart of Proxima c using multi-epoch high-contrast SPHERE data at VLT 
      Gratton, R.; Zurlo, A.; Le Coroller, H.; Damasso, M.; Sordo, F. del; Langlois, M.; Mesa, D.; Milli, J.; Chauvin, Gaël; Desidera, S.; Hagelberg, J.; Lagadec, E.; Vigan, A.; Boccaletti, A.; Bonnefoy, M.; Brandner, W.; Brown, S.; Cantalloube, F.; Delorme, P.; Orazi, V.

      Context. Proxima Centauri is the closest star to the Sun and it is known to host an Earth-like planet in its habitable zone; very recently a second candidate planet was proposed based on radial velocities. At quadrature, ...
    • The search for disks or planetary objects around directly imaged companions: A candidate around DH Tau B.
