    • An 80 au cavity in the disk around HD 34282 
      Van der Plas, Gerrit; Menard, F.; Canovas, H.; Avenhaus, H.; Casassus Montero, Simón; Pinte, Christophe; Cáceres, C.; Cieza, L. (EDP Sciences, 2017)
      Context. Large cavities in disks are important testing grounds for the mechanisms proposed to drive disk evolution and dispersion, such as dynamical clearing by planets and photoevaporation. Aims. We aim to resolve the ...
    • Cavity and other radial substructures in the disk around HD 97048 
      Van Der Plas, G.; Wright, C. M.; Ménard, F.; Casassus Montero, Simón; Cánovas, H.; Pinte, C.; Maddison, S. T.; Maaskant, K.; Avenhaus, H.; Cieza, L.; Pérez, S.; Ubach, C. (EDP Sciences, 2017)
      Context. Gaps, cavities, and rings in circumstellar disks are signposts of disk evolution and planet-disk interactions. We follow the recent suggestion that Herbig Ae/Be disks with a flared disk harbor a cavity, and ...
    • Gas Inside the 97 AU Cavity around the Transition Disk Sz 91 
      Canovas, H.; Schreiber, M. R.; Cáceres, C.; Ménard, Francois; Pinte, Christophe; Mathews, G.; Cieza, L.; Casassus Montero, Simón; Hales, A.; Williams, J. P.; Román, P.; Hardy, A. (The American Astronomical Society, 2015-05-20)
      We present ALMA (Cycle 0) band 6 and band 3 observations of the transition disk Sz 91. The disk inclination and position angle are determined to be i = 49◦ . 5 ± 3◦ . 5°and PA = 18◦ . 2 ± 3◦ . 5 and the dusty and ...
    • Homogeneous analysis of the dust morphology of transition disks observed with ALMA: investigating dust ... 
      Pinilla, P.; Tazzari, M.; Pascucci, I.; Youdin, A. N.; Garufi, A.; Manara, C. F.; Testi, L.; Van der Plas, Gerrit; Barenfeld, S. A.; Canovas, H.; Cox, E. G.; Hendler, N. P.; Pérez, L. M.; van der Marel, N. (Iop Publishing LTD., 2018-05-20)
      We analyze the dust morphology of 29 transition disks (TDs) observed with Atacama Large (sub-)Millimeter Array (ALMA) at (sub-)millimeter emission. We perform the analysis in the visibility plane to characterize the total ...
    • The inner environment of Z Canis Majoris: High-contrast imaging polarimetry with NaCo 
      Canovas, H.; Pérez, Sebastián; Dougados, C.; de Boer, J.; Ménard, Francois; Casassus Montero, Simón; Schreiber, M. R.; Cieza, L. A.; Caceres, C.; Girard, J. H. (EDP SCIENCES, 2015)
      Context. Z CMa is a binary composed of an embedded Herbig Be and an FU Ori class star separated by ∼100 au. Observational evidence indicates a complex environment in which each star has a circumstellar disk and drives a ...
