    • Observations of gas flows inside a protoplanetary gap 
      Van der Plas, Gerrit; Pérez M., Sebastián; Dent, William R. F.; Fomalont, Ed; Hagelberg, Janis; Hales, Antonio; Jordán, Andrés; Mawet, Dimitri; Ménard, Francois; Wootten, Al; Wilner, David; Hughes, A. Meredith; Schreiber, Matthias R.; Girard, Julien H.; Ercolano, Bárbara; Canovas, Héctor; Román, Pablo E.; Casassus Montero, Simón; Salinas, Vachail (Nature Publishing Group, 2013-01-10)
      The formation of gaseous giant planets is thought to occur in the first few million years after stellar birth. Models1 predict that the process produces a deep gap in the dust component (shallower in the gas2, 3, 4). ...
    • On the nature of the tertiary companion to FW Tau: ALMA CO observations and SED modeling 
      Cáceres, Claudio; Hardy, Adam; Schreiber, Matthias R.; Cánovas, Héctor; Cieza, Lucas A.; Williams, Jonathan P.; Hales, Antonio; Pinte, Christophe; Ménard, Francois; Wahhaj, Zahed (IOP Publishing, 2015)
      It is thought that planetary mass companions may form through gravitational disk instabilities or core accretion. Identifying such objects in the process of formation would provide the most direct test for the competing ...
    • Probing the final stages of protoplanetary disk evolution with ALMA 
      Hardy, Adam; Cáceres, C.; Schreiber, Matthias R.; Cieza González, Lucas; Alexander, R. D.; Cánovas, H.; Williams, Jonathan P.; Wahhaj, Zahed; Ménard, Francois (EDP Sciences, 2015)
      Context. The evolution of a circumstellar disk from its gas-rich protoplanetary stage to its gas-poor debris stage is not understood well. It is apparent that disk clearing progresses from the inside-out on a short time ...
    • A ring-like concentration of mm-sized particles in Sz 91 
      Cánovas, Héctor; Cáceres, C.; Schreiber, Matthias R.; Hardy, Adam; Cieza González, Lucas; Ménard, Francois; Hales, Antonio (Oxford Univ Press, 2016)
      Models of planet formation and disc evolution predict a variety of observables in the dust structure of protoplanetary discs. Here, we present Atacama Large Millimeter/submillimeter Array (ALMA) Band-6 and Band-7 observations ...
    • Sparse aperture masking observations of the FL Cha pre-transitional disk 
      Cieza, Lucas A.; Lacour, Sylvestre; Schreiber, Matthias R.; Casassus Montero, Simón; Jordán, Andrés; Mathews, Geoffrey S.; Cánovas, Héctor; Ménard, Francois; Kraus, Adam L.; Pérez, Sebastián; Tuthill, Peter; Ireland, Michael J. (The American Astronomical Society, 2013)
      We present deep Sparse Aperture Masking (SAM) observations obtained with the ESO Very Large Telescope of the pre-transitional disk object FL Cha (SpT = K8, d = 160 pc), the disk of which is known to have a wide optically thin ...
    • The characterization of the dust content in the ring around Sz 91: indications of planetesimal formation? 
      Mauco, Karina; Carrasco González, Carlos; Schreiber, Matthias R.; Sierra, Aníbal; Olofsson, Johan; Bayo, Amelia; Cáceres, Claudio; Cánovas, Héctor; Palau, Aina (IOP, 2021)
      One of the most important questions in the field of planet formation is how millimeter- and centimeter-sized dust particles overcome radial drift and fragmentation barriers to form kilometer-sized planetesimals. ...
