    • ALMA Observations of Elias 2-24: A Protoplanetary Disk with Multiple Gaps in the Ophiuchus Molecular Cloud 
      Cieza, Lucas; Casassus Montero, Simón; Pérez, Sebastián; Hales, Antonio; Cárcamo, Miguel; Ansdell, Megan; Avenhaus, Henning; Bayo, Amelia; Bertrang, Gesa; Cánovas, Hector; Christiaens, Valentin; Dent, William; Ferrero, Gabriel; Gamen, Roberto; Olofsson, Johan; Orcajo, Santiago; Osses, Axel; Peña-Ramirez, Karla; Principe, David; Ruíz-Rodríguez, Dary; Schreiber, Matthias; Van der Plas, Gerrit; Williams, Jonathan; Zurlo, Alice (Institute of Physics Publishing, 2017)
      We present ALMA 1.3 mm continuum observations at 0."2 (25 au) resolution of Elias 2-24, one of the largest andbrightest protoplanetary disks in the Ophiuchus Molecular Cloud, and we report the presence of three partiallyresolved ...
    • Imaging the water snow-line during a protostellar outburst 
      Cieza González, Lucas; Casassus Montero, Simón; Tobin, John; Bos, Steven; Williams, Jonathan; Pérez, Sebastián; Zhu, Zhaohuan; Canovas, Héctor; Dunham, Michael; Hales, Antonio; Prieto, José; Principe, David; Schreiber, Matthias; Ruiz Rodríguez, Dary; Zurlo, Alice (Nature Publishing Group, 2016)
      A snow-line is the region of a protoplanetary disk at which a major volatile, such as water or carbon monoxide, reaches its condensation temperature. Snow-lines play a crucial role in disk evolution by promoting the rapid ...
    • Resolving the FU Orionis System with ALMA: Interacting Twin Disks? 
      Pérez Márquez, Sebastián; Hales, Antonio; Liu, Hauyu Baobab; Zhu, Zhaohuan; Casassus Montero, Simón; Williams, Jonathan; Zurlo, Alice; Cuello, Nicolás; Cieza, Lucas; Príncipe, David (IOP, 2020)
      FU Orionis objects are low-mass pre-main sequence stars characterized by dramatic outbursts several magnitudes in brightness. These outbursts are linked to episodic accretion events in which stars gain a significant portion ...
    • The ALMA early science view of FUor/EXor objects - IV. Misaligned outflows in the complex star-forming ... 
      Principe, David; Cieza, Lucas; Hales, Antonio; Zurlo, Alice; Williams, Jonathan; Ruíz-Rodríguez, Dary; Canovas, Héctor; Casassus Montero, Simón; Mužić, Koraljka; Pérez, Sebastián; Tobin, John; Zhu, Zhaohuan (Oxford University Press, 2017)
      We present Atacama Large Millimeter/sub-millimeter Array (ALMA) observations of the star-forming environment surrounding V1647 Ori, an outbursting FUor/EXor pre-MS star. Dust continuum and the (J = 2 − 1) 12CO, 13CO, ...
    • The ALMA early science view of FUor/EXor objects – I. Through the looking-glass of V2775 Ori 
      Zurlo, Alice; Cieza, Lucas; Williams, Jonathan; Canovas, Hector; Pérez González, Sebastián; Hales, Antonio; Muzic, Koraljka; Principe, David; Ruíz-Rodríguez, Dary; Tobin, John; Zhu, Zhaohuan; Casassus Montero, Simón; Aliste Prieto, José (Royal Astronomical Society, 2017)
      As part of an Atacama Large Millimeter/submillimiter Array (ALMA) survey to study the origin of episodic accretion in young eruptive variables, we have observed the circum-stellar environment of the star V2775 Ori. This ...
