(EDP Sciences, 2018)
      Context. Young circumstellar disks are the birthplaces of planets. Their study is of prime interest to understand the physical and chemical conditions under which planet formation takes place. Only very few detections of ...
    • 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 ...
    • Probing protoplanetary disk evolution in the Chamaeleon II region 
      Villenave, M.; Ménard, F.; Dent, W. R. F.; Benisty, Myriam; Van der Plas, G.; Williams, J. P.; Ansdell, M.; Ribas, A.; Cáceres, C.; Cánovas, H.; Cieza, L.; Hales, A.; Kamp, I.; Pinte, C.; Principe, D. A.; Schreiber, M. R. (EDP Sciences, 2021)
      Context. Characterizing the evolution of protoplanetary disks is necessary to improve our understanding of planet formation. Constraints on both dust and gas are needed to determine the dominant disk dissipation ...
    • Water vapor in the protoplanetary disk of DG Tau 
      Podio, L.; Kamp, I.; Codella, C.; Cabrit, S.; Nisini, B.; Dougados, C.; Sandell, G.; Williams, J. P.; Testi, L.; Thi, W. F.; Woitke, P.; Meijerink, R.; Spaans, M.; Aresu, G.; Ménard, Francois; Pinte, Christophe (The American Astronomical Society, 2013)
      Water is key in the evolution of protoplanetary disks and the formation of comets and icy/water planets. While high-excitation water lines originating in the hot inner disk have been detected in several T Tauri stars ...
