    • 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 ...
    • Circumbinary, not transitional: on the spiral arms, cavity, shadows, fast radial flows, streamers, and ... 
      Price, Daniel J.; Cuello, Nicolás; Pinte, Christophe; Mentiplay, Daniel; Casassus Montero, Simón; Christiaens, Valentin; Kennedy, Grant M.; Cuadra, Jorge; Pérez M., Sebastián; Marino, Sebastian; Armitage, Philip J.; Zurlo, Alice; Juhasz, Attila; Ragusa, Enrico; Laibe, Guillaume; Lodato, Giuseppe (Oxford University Press, 2018)
      We present 3D hydrodynamical models of the HD 142527 protoplanetary disc, a bright and well-studied disc that shows spirals and shadows in scattered light around a 100 au gas cavity, a large horseshoe dust structure in mm ...
    • Classical T-Tauri stars with VPHAS+: II: NGC6383 in Sh 2-012 
      Kalari, V. M. (Oxford Univ Press, 2019)
      This paper presents optical (ugriH alpha)-infrared (JHKs, 3.6-8.0 mu m) photometry and Gaia astrometry of 55 Classical T-Tauri stars (CTTS) in the star-forming region Sh 2-012 and its central cluster NGC6383. The sample ...
    • 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 ...

    • The virial factor and biases in single epoch black hole mass determinations 
      Mejía Restrepo, Julián; Lira Teillery, Paulina; Netzer, Hagai; Trakhtenbrot, Benny; Capellupo, Daniel (Frontiers media SA, 2018)
      Accurately determining the masses of supermassive black holes is crucial to understand their evolution and the establishment of their relationship with their host galaxy properties. Beyond the local universe, the single ...
