    • 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 ...
    • 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. ...
