    • Asymmetric features in the protoplanetary disk MWC 758 
      Benisty, Myriam; Juhasz, A.; Boccaletti, A.; Avenhaus, H.; Milli, J.; Thalmann, C.; Dominik, C.; Pinilla, P.; Buenzli, E.; Pohl, A.; Beuzit, J.L.; Birnstiel, T.; Boer, J. de; Bonnefoy, M.; Chauvin, G.; Christiaens, V.; Garufi, A.; Grady, C.; Henning, Thomas; Huelamo, N.; Isella, A.; Langlois, M.; Ménard, Francois; Mouillet, D.; Olofsson, J.; Pantin, E.; Pinte, Christophe; Pueyo, L. (ESO, 2015)
      Context. The study of dynamical processes in protoplanetary disks is essential to understand planet formation. In this context, transition disks are prime targets because they are at an advanced stage of disk clearing and ...
    • Narrow belt of debris around the Sco-Cen star HD 141011 
      Bonnefoy, M.; Milli, J.; Menard, F.; Delorme, P.; Chomez, A.; Bonavita, M.; Lagrange, A-M; Vigan, A.; Augereau, J. C.; Beuzit, J. L.; Biller, B.; Boccaletti, A.; Chauvin, G.; Desidera, S.; Faramaz, V.; Galicher, R.; Gratton, R.; Hinkley, S.; Lazzoni, C.; Matthews, E.; Mesa, D.; Mordasini, C.; Mouillet, D.; Olofsson, J.; Pinte, C. (EDP Sciences, 2021)
      Context. We initiated a deep-imaging survey of Scorpius-Centaurus A-F stars in 2015. These stars are predicted to host warm inner and cold outer belts of debris reminiscent of the architecture of emblematic systems such ...
    • Optical Imaging Polarimetry of the LkCa 15 protoplanetary Disk with Sphere Zimpol 
      Thalmann, C.; Mulders, G. D.; Janson, M.; Olofsson, J.; Benisty, Myriam; Avenhaus, H.; Quanz, S. P.; Schmid, H. M.; Henning, Thomas; Buenzli, E.; Ménard, Francois; Carson, J. C.; Garufi, A.; Messina, S.; Dominik, C.; Leisenring, J.; Chauvin, G.; Meyer, M. R. (IOP Publishing, 2015)
      We present the first optical (590-890 nm) imaging polarimetry observations of the pre-transitional protoplanetary disk around the young solar analog LkCa 15, addressing a number of open questions raised by previous studies. ...
    • Sculpting the disk around T Chamaeleontis: an interferometric view 
      Olofsson, J.; Benisty, Myriam; Le Bouquin, J. B.; Berger, J. P; Lacour, S.; Ménard, Francois; Henning, Thomas; Crida, A.; Burtscher, L.; Meeus, G.; Ratzka, T.; Pinte, Christophe; Augereau, J. C.; Malbet, F.; Lazare, B.; Traub, W. (EDP Sciences, 2013)
      Context. Circumstellar disks are believed to be the birthplace of planets and are expected to dissipate on a timescale of a few Myr. The processes responsible for the removal of the dust and gas will strongly modify the ...
    • The HD 98800 quadruple pre-main sequence system Towards full orbital characterisation using long-baseline ... 
      Zúñiga Fernández, S.; Olofsson, J.; Bayo, A.; Haubois, X.; Corral Santana, J. M.; Lopera Mejía, A.; Ronco, M. P.; Tokovinin, A.; Gallenne, Alexandre; Kennedy, G. M.; Berger, J. P. (EDP, 2021)
      Context. HD 98800 is a young (∼10 Myr old) and nearby (∼45 pc) quadruple system, composed of two spectroscopic binaries orbiting around each other (AaAb and BaBb), with a gas-rich disk in polar configuration around BaBb. ...
