    • 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 ...
    • Exploring the R CrA environment with SPHERE: Discovery of a new stellar companion 
      Mesa, D.; Bonnefoy, M.; Gratton, R.; Van Der Plas, G.; D'Orazi, V.; Sissa, E.; Zurlo, A.; Rigliaco, E.; Schmidt, T.; Langlois, M.; Vigan, A.; Ubeira Gabellini, M. G.; Desidera, S.; Antoniucci, S.; Barbieri, M.; Benisty, Myriam; Boccaletti, A.; Claudi, R.; Fedele, D.; Gasparri, (EDP Sciences, 2019)
      Aims. R Coronae Australis (R CrA) is the brightest star of the Coronet nebula of the Corona Australis (CrA) star forming region. This star is very red in color, probably due to dust absorption, and is strongly variable. ...
    • 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 ...
