    • 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 ...
    • Flybys in protoplanetary discs – II. Observational signatures 
      Cuello, Nicolás; Louvet, Fabien; Mentiplay, Daniel; Pinte, Christophe; Price, Daniel J.; Winter, Andrew J.; Nealon, Rebecca; Menard, Francois; Lodato, Giuseppe; Dipierro, Giovanni; Christiaens, Valentín; Montesinos, Matías; Cuadra, Jorge; Laibe, Guillaume; Cieza, Lucas; Dong, Ruobing; Alexander, Richard (Oxford, 2020)
      Tidal encounters in star clusters perturb discs around young protostars. In Cuello et al., we detailed the dynamical signatures of a stellar flyby in both gas and dust. Flybys produce warped discs, spirals with evolving ...
    • 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 ...
    • 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 ...
    • The ice composition in the disk around V883 Ori revealed by its stellar outburst 
      Lee, Jeong Eun; Lee, Seokho; Baek, Giseon; Aikawa, Yuri; Cieza, Lucas; Yoon, Sung Yong; Herczeg, Gregory; Johnstone, Doug; Casassus Montero, Simón (Nature Publishing Group, 2019)
      © 2019, The Author(s), under exclusive licence to Springer Nature Limited. Complex organic molecules (COMs), which are the seeds of prebiotic material and precursors of amino acids and sugars, form in the icy mantles of ...
