    • 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 ...
    • Ground-based transit observations of the super-Earth GJ 1214 b , 
      Cáceres, C.; Kabath, P.; Hoyer, S.; Ivanov, V. D.; Rojo, Patricio; Girard, J. H.; Miller Ricci, E.; Fortney, J. J.; Minniti, D. (EDP, 2014)
      Context. GJ 1214 b is one of the few known transiting super-Earth-sized exoplanets with a measured mass and radius. It orbits an M-dwarf, only 14.55 pc away, making it a favorable candidate for follow-up studies. However, ...
    • 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 ...
    • 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 ...
