    • A tale of two transition disks: alma long-baseline observations of iso-oph 2 reveal two closely packed ... 
      González Ruilova, Camilo; Cieza, Lucas A.; Hales, Antonio S.; Pérez, Sebastián; Zurlo, A.; Arce Tord, Carla; Casassus Montero, Simón; Canovas, Héctor; Flock, Mario; Herczeg, Gregory J.; Pinilla, Paola; Price, Daniel J.; Príncipe, David A.; Ruiz Rodríguez, Dary; Williams, Jonathan P. (IOP Publishing, 2020)
      ISO-Oph 2 is a wide-separation (240 au) binary system where the primary star harbors a massive (M-dust similar to 40M(circle plus)) ring-like disk with a dust cavity similar to 50 au in radius and the secondary hosts a ...
    • Large-scale CO Spiral Arms and Complex Kinematics Associated with the T Tauri Star RU Lup 
      Huang, Jane; Andrews, Sean M.; Oberg, Karin I.; Ansdell, Megan; Benisty, Myriam; Carpenter, John M.; Isella, Andrea; Pérez Muñoz, Laura; Ricci, Luca; Williams, Jonathan P.; Wilner, David J.; Zhu, Zhaohuan (IOP, 2020)
      While protoplanetary disks often appear to be compact and well organized in millimeter continuum emission, CO spectral line observations are increasingly revealing complex behavior at large distances from the host star. ...
    • The ALMA early science view of FUor/EXor objects - V. Continuum disc masses and sizes 
      Cieza, Lucas A.; Ruiz Rodriguez, Dary; Pérez, Sebastián; Casassus Montero, Simón; Williams, Jonathan P.; Zurlo, Alice; Principe, David A.; Hales, Antonio; Prieto, Jose L.; Tobin, John J.; Zhu, Zhaohuan; Marino, Sebastián (Oxford University Press, 2018)
      Low-mass stars build a significant fraction of their total mass during short outbursts of enhanced accretion known as FUor and EXor outbursts. FUor objects are characterized by a sudden brightening of similar to 5 mag at ...
    • The Ophiuchus DIsc Survey Employing ALMA (ODISEA) - I: Project description and continuum images at 28 au resolution 
      Cieza, Lucas A.; Ruíz-Rodríguez, Dary; Hales, Antonio; Casassus Montero, Simón; Pérez, Sebastian; Gonzalez-Ruilova, Camilo; Cánovas, Hector; Williams, Jonathan P.; Zurlo, Alice; Ansdell, Megan; Avenhaus, Henning; Bayo, Amelia; Bertrang, Gesa H.M.; Christiaens, Valentin; Dent, (Oxford University Press, 2019)
      © 2018 The Author(s). Published by Oxford University Press on behalf of the Royal Astronomical Society. We introduce the Ophiuchus DIsc Survey Employing ALMA (ODISEA), a project aiming to study the entire population of ...
    • The Ophiuchus DIsc Survey Employing ALMA (ODISEA) – II. The effect of stellar multiplicity on disc properties 
      Zurlo, Alice; Cieza, Lucas A.; Pérez, Sebastián; Christiaens, Valentín; Williams, Jonathan P.; Guidi, Greta; Cánovas, Héctor; Casassus Montero, Simón; Hales Gebrim, Antonio; Principe, David A.; Ruíz Rodríguez, Dary; Fernández Figueroa, Antonia (Oxford University Press, 2020)
      We present adaptive optics (AO) near-infrared (NIR) observations using VLT/NACO and Keck/NIRC2 of Ophiuchus DIsc Survey Employing ALMA (ODISEA) targets. ODISEA is an ALMA survey of the entire population of circumstellar ...
