    • Accretion kinematics through the warped transition disk in hd142527 from resolved CO(6-5) observations 
      Casassus Montero, Simón; Marino Estay, Sebastián; Pérez, S.; Román, P.; Dunhill, A.; Armitage, P. J.; Cuadra, J.; Wootten, A.; Van der Plas, Gerrit; Cieza, L.; Moral, Víctor; Christiaens, V.; Montesinos, Matías (IOP Publishing, 2015)
      The finding of residual gas in the large central cavity of the HD 142527 disk motivates questions regarding the origin of its non-Keplerian kinematics and possible connections with planet formation. We aim to understand ...
    • Co gas inside the protoplanetary disk cavity in HD142527: disk structure from ALMA 
      Pérez, S.; Casassus Montero, Simón; Ménard, Francois; Román, P.; Van der Plas, Gerrit; Cieza, L.; Pinte, Christophe; Christiaens, V.; Hales, A. (IOP Pub, 2015)
      Inner cavities and annular gaps in circumstellar disks are possible signposts of giant planet formation. The young star HD142527 hosts a massive protoplanetary disk with a large cavity that extends up to 140 AU from the ...
    • 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 ...
    • A SCUBA-2 850-μm survey of protoplanetary discs in the IC 348 cluster 
      Cieza, L.; Williams, J.; Kourkchi, E.; Andrews, S.; Casassus Montero, Simón; Graves, S.; Schreiber, M. (Royal Astronomical Society, 2015)
      We present 850-µm observations of the 2–3 Myr cluster IC 348 in the Perseus molecular cloud using the SCUBA-2 camera on the James Clerk Maxwell Telescope. Our SCUBA-2 map has a diameter of 30 arcmin and contains ∼370 ...
    • The Circumstellar Disk and Asymmetric Outflow of the EX Lup Outburst System 
      Hales, A. S.; Pérez, S.; Saito, M.; Pinte, C.; Knee, L. B. G.; De Gregorio Monsalvo, Itziar; Dent, B.; López, C.; Plunkett, A.; Cortés, P.; Corder, S.; Cieza, L. (Institute of Physics Publishing, 2018)
      We present Atacama Large Millimeter/submillimeter Array (ALMA) observations at 0farcs3 resolution of EX Lup, the prototype of the EXor class of outbursting pre-main-sequence stars. The circumstellar disk of EX Lup is ...
