    • 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 ...
    • 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 ...
    • 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 ...

      © 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 ...
