    • A search for accreting young companions embedded in circumstellar disks: High-contrast H α imaging with VLT/SPHERE 
      Cugno, G.; Quanz, S. P.; Hunziker, S.; Stolker, T.; Schmid, H. M.; Avenhaus, H.; Baudoz, P.; Bohn, A. J.; Bonnefoy, M.; Buenzli, E.; Chauvin, G.; Cheetham, A.; Desidera, S.; Dominik, C.; Feautrier, P.; Feldt, M.; Ginski, C.; Girard, J. H.; Gratton, R.; Hagelberg, J.; Hugot, (EDP Sciences, 2019)
      Context. In recent years, our understanding of giant planet formation progressed substantially. There have even been detections of a few young protoplanet candidates still embedded in the circumstellar disks of their host ...
    • 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 ...
    • Gap, shadows, spirals, and streamers: SPHERE observations of binary-disk interactions in GG Tauri A 
      Keppler, M.; Penzlin, A.; Benisty, Myriam; van Boekel, R.; Henning, T.; Van Holstein, R. G.; Kley, W.; Garufi, A.; Ginski, C.; Brandner, W.; Bertrang, Gesa H. M.; Boccaletti, A.; de Boer, J.; Bonavita, M.; Brown Sevilla, S.; Chauvin, Gael Epely; Dominik, C.; Janson, M.; Langlois, M.; Lodato, G.; Maire, A. L.; Ménard, F.; Pantin, E.; Pinte, C.; Stolker, T.; Szulágyi, J.; Thebault, P.; Villenave, M.; Zurlo, A.; Rabou, P.; Feautrier, P.; Feautrier, P.; Feldt, M.; Madec, F.; Wildi, F. (EDP Science, 2020)
      Context. A large portion of stars is found to be part of binary or higher-order multiple systems. The ubiquity of planets found around single stars raises the question of whether and how planets in binary systems form. ...
    • 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 ...
    • SPHERE dynamical and spectroscopic characterization of HD 142527B 
      Claudi, R.; Maire, A.-L.; Mesa, D.; Cheetham, A.; Fontanive, C.; Gratton, R.; Zurlo, A.; Avenhaus, H.; Bhowmik, T.; Biller, B.; Boccaletti, A.; Bonavita, M.; Bonnefoy, M.; Cascone, E.; Chauvin, G.; Delboulbé, A.; Desidera, S.; D'Orazi, V.; Feautrier, P.; Feldt, M.; Flammini (EDP Sciences, 2019)
      Aims. HD 142527 is one of the most frequently studied Herbig Ae/Be stars with a transitional disk that hosts a large cavity that is up to about 100 au in radius. For this reason, it has been included in the guaranteed time ...
    • The search for disks or planetary objects around directly imaged companions: A candidate around DH Tau B. 
      Lazzoni, C.; Zurlo, A.; Desidera, S.; Mesa, D.; Fontanive, C.; Bonavita, M.; Ertel, S.; Rice, K.; Vigan, A.; Boccaletti, A.; Bonnefoy, M.; Chauvin, Gaël; Delorme, P.; Gratton, R.; Houllé, M.; Maire, A.L.; Meyer, M.; Rickman, E.; Spalding, E.

L.; Biller, B.; Brandner, W.; Buenzli, E.; Cantalloube, F.; Cheetham, A.; Cudel, M.; Feldt, M.; Galicher, R.; Janson, M.; Hagelberg, J.; Henning, T.; Kasper, M.; Keppler, M.; Lagrange, A. M; Lannier, J.; LeCoroller, H.; Mouillet, D.; Peretti, S.; Perrot, C.; Salter, G.; Samland, M.; Schmidt, T.; Sissa, E.; Wildi, F. (EDP Science, 2020)
      Context. In recent decades, thousands of substellar companions have been discovered with both indirect and direct methods of detection. While the majority of the sample is populated by objects discovered using radial ...
