    • ALMA reveals a candidate hot and compact disc around the O-type protostar IRAS 16547−4247 
      Zapata, Luis A.; Palau, Aina; Galván Madrid, Roberto; Rodríguez, Luis F.; Garay Brignardello, Guido; Morán, James M.; Franco Hernández, Ramiro (Oxford University Press, 2015)
      We present high angular resolution (similar to 0.3 arcsec) submillimeter continuum (0.85 mm) and line observations of the O-type protostar IRAS 16547-4247 carried out with the Atacama Large Millimeter/Submillimeter Array ...
    • A co survey in planet-forming disks: characterizing the gas content in the epoch of planet formation 
      Hales, A.; De Gregorio Monsalvo, Itziar; Montesinos, B.; Casassus Montero, Simón; Dent, William R. F.; Dougados, Catherine; Eiroa, C.; Hughes, A.M.; Garay Brignardello, Guido; Mardones Pérez, Diego; Ménard, Francois; Palau, Aina; Pérez, Sebastián; Phillips, N.; Torrelles, J. M.; Wilner, D. (The American Astronomical Society., 2014-07-31)
      We carried out a 12CO(3-2) survey of 52 southern stars with a wide range of IR excesses (L IR/L *) using the single-dish telescopes APEX and ASTE. The main aims were (1) to characterize the evolution of molecular gas in ...
    • Deciphering the ionized gas content in the massive star-forming complex G75.78+0.34 
      Sánchez Monge, Álvaro; Kurtz, Stan; Palau, Aina; Estalella, Robert; Shepherd, Debra; Lizano, Susana; Franco, José; Garay Brignardello, Guido (2013-04-01)
      We present subarcsecond observations toward the massive star-forming region G75.78+0.34. We used the Very Large Array to study the centimeter continuum and H2O and CH3OH maser emission, and the Owens Valley Radio Observatory ...
    • Gravity or turbulence? - III. Evidence of pure thermal Jeans fragmentation at similar to 0.1 pc scale 
      Palau, Aina; Ballesteros Paredes, Javier; Vázquez Semadeni, Enrique; Sánchez Monge, Álvaro; Estalella, Robert; Fall, S. Michael; Zapata, Luis A.; Camacho, Vianey; Gómez, Laura; Naranjo Romero, Raúl; Busquet, Gemma; Fontani, Francesco (Oxford University Press, 2015)
      We combine previously published interferometric and single-dish data of relatively nearby massive dense cores that are actively forming stars to test whether their 'fragmentation level' is controlled by turbulent or thermal ...
    • 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. ...
