    • Astrometric and photometric accuracies in high contrast imaging: The SPHERE speckle calibration tool (SpeCal) 
      Galicher, R.; Boccaletti, A.; Mesa, D.; Delorme, P.; Gratton, R.; Langlois, Maud; Lagrange, Anne Marie; Maire, A.-L.; Le Coroller, H.; Chauvin, G.; Biller, Beth; Cantalloube, Faustine; Janson, Markus; Lagadec, E.; Meunier, N.; Vigan, Arthur; Hagelberg, Janis; Bonnefoy, Mickael; Zurlo, Alice; Rocha, S.; Maurel, D.; Jaquet, M.; Buey, T.; Weber, L. (EDP Sciences, 2018-07-19)
      Context. The consortium of the Spectro-Polarimetric High-contrast Exoplanet REsearch installed at the Very Large Telescope (SPHERE/VLT) has been operating its guaranteed observation time (260 nights over five years) since ...
    • First millimeter detection of the disk around a young, isolated, planetary-mass object 
      Bayo, Amelia; Joergens, Viki; Liu, Yao; Brauer, Robert; Olofsson, Johan; Arancibia, Javier; Pinilla, Paola; Wolf, Sebastian; Ruge, Jan Philipp; Henning, Thomas; Natta, Antonella; Johnston, Katharine G.; Bonnefoy, Mickael; Beuther, Henrik; Chauvin, G. (IOP Publishing, 2017-05-20)
      OTS44 is one of only four free-floating planets known to have a disk. We have previously shown that it is the coolest and least massive known free-floating planet (similar to 12 M-Jup) with a substantial disk that is ...
    • First resolved observations of a highly asymmetric debris disc around HD 160305 with VLT/SPHERE 
      Perrot, Clément; Thebault, Philippe; Lagrange, Anne Marie; Boccaletti, Anthony; Vigan, Arthur; Desidera, Silvano; Ausgereau, Jean Charles; Bonnefoy, Mickael; Choquet, Élodie; Kral, Quentin; Loh, Alan; Maire, Anne Lise; Ménard, Francois; Messina, Sergio; Olofsson, Johan (EDP Sciences, 2019)
      Context. Direct imaging of debris discs gives important information about their nature, their global morphology, and allows us to identify specific structures possibly in connection with the presence of gravitational ...
    • VLT/SPHERE survey for exoplanets around young early-type stars, including systems with multi-belt architectures 
      Lombart, Maxime; Chauvin, Gael Epely; Rojo Rubke, Patricio; Lagadec, Eric; Delorme, Philippe; Beust, Herve; Bonnefoy, Mickael; Galicher, Raphael; Gratton, Raffaele; Mesa, Dino; Bonavita, Mariangela; Allard, France; Bayo, Alberto; Boccaletti, Anthony; Desidera, Silvano; Girard, Julien; Jenkins, James Stewart; Klahr, H.; Laibe, G.; Lagrange, Anne Marie; Lazzoni, C.; Marleau, Gabriel Dominique; Minniti, Dante; Mordasini, C. (EDP Science, 2020)
      Context. Dusty debris disks around pre- and main-sequence stars are potential signposts for the existence of planetesimals and exoplanets. Giant planet formation is therefore expected to play a key role in the evolution ...
