    • 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 ...
