    • An inner warp in the DoAr 44 T Tauri transition disc 
      Casassus Montero, Simón; Avenhaus, Henning; Pérez, Sebastián; Navarro, Víctor; Cárcamo, Miguel; Marino, Sebastián; Cieza, Luca; Quanz, Sascha P.; Alarcón, Felipe; Zurlo, Alice; Osses Alvarado, Axel; Rannou, Fernando R.; Román, Pablo E.; Barraza, Marcelo (Oxford University Press, 2018-07)
      Optical/IR images of transition discs (TDs) have revealed deep intensity decrements in the rings of HAeBes HD 142527 and HD 100453 that can be interpreted as shadowing from sharply tilted inner discs, such that the outer ...
    • Cm-wavelength observations of MWC 758: Resolved dust trapping in a vortex 
      Casassus Montero, Simón; Marino, Sebastián; Lyra, Wladimir; Baruteau, Clément; Vidal, Matías; Wootten, Alwyn; Pérez, Sebastián; Alarcon, Felipe; Barraza, Marcelo; Cárcamo, Miguel; Dong, Ruobing; Sierra, Anibal; Zhu, Zhaohuan; Ricci, Luca; Christiaens, Valentin; Cieza, Lucas (Oxford University Press, 2019)
      © 2018 The Author(s)The large crescents imaged by ALMA in transition discs suggest that azimuthal dust trapping concentrates the larger grains, but centimetre–wavelengths continuum observations are required to map the ...
    • Cooling in the shade of warped transition discs 
      Casassus Montero, Simón; Pérez, Sebastián; Osses, Axel; Marino, Sebastián (Oxford University Press, 2019)
      © 2019 The Author(s).The mass of the gaseous reservoir in young circumstellar discs is a crucial initial condition for the formation of planetary systems, but estimates vary by orders of magnitude. In some discs with ...
    • Erratum: Cooling in the shade of warped transition disks 
      Casassus Montero, Simón; Pérez, Sebastián; Osses Alvarado, Axel; Marino, Sebastián (Oxford University Press, 2020)
      This is an Erratum to the paper ‘Cooling in the shade of warped transition disks’ that was published in MNRAS, 486, L58-L62 (2019). The x-axis of Fig. 1 in the original version of the paper is incorrectly labeled, the ...
    • Long baseline observations of the HD 100546 protoplanetary disk with ALMA 
      Peréz Márquez, Sebastián; Casassus Montero, Simón; Hales, Antonio; Marino, Sebastián; Cheetham, Anthony; Zurlo, Alice; Cieza, Lucas; Dong, Ruobing; Alarcón, Felipe; Benítez Llambay, Pablo; Fomalont, Ed; Avenhaus, Henning (IOP, 2020)
      Using the Atacama Large Millimeter/submillimeter Array, we observed the young Herbig star HD 100546, host to a prominent disk with a deep, wide gap in the dust. The high-resolution 1.3 mm continuum observation reveals fine ...
    • Spiral waves triggered by shadows in transition disks 
      Montesinos, Matías; Pérez, Sebastián; Casassus Montero, Simón; Marino, Sebastián; Cuadra, Jorge; Christiaens, Valentín (IOP Publishing, 2016)
      Circumstellar asymmetries such as central warps have recently been shown to cast shadows on outer disks. We investigate the hydrodynamical consequences of such variable illumination on the outer regions of a transition ...
    • 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 ...
