    • A decade of MWC 758 disk images: where are the spiral arm driving planets? 
      Ren, Bin; Dong, Ruobing; Esposito, Thomas M.; Pueyo, Laurent; Debes, John H.; Poteet, Charles A.; Choquet, Elodie; Benisty, Myriam; Chiang, Eugene; Grady, Carol A.; Hines, Dean C.; Schneider, Glenn; Soummer, Remi (IOP Publishing Ltd, 2018)
      Large-scale spiral arms have been revealed in scattered light images of a few protoplanetary disks. Theoretical models suggest that such arms may be driven by and corotate with giant planets, which has called for remarkable ...
    • 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 ...
    • Dynamical evidence of a spiral arm–driving planet in the MWC 758 protoplanetary disk 
      Ren, Bin; Dong, Ruobing; van Holstein, Rob G.; Ruffio, Jean Baptiste; Calvin, Benjamín A.; Girard, Julien H.; Benisty, Myriam; Boccaletti, Anthony; Espósito, Thomas M.; Choquet, Elodie; Mawet, Dimitri; Pueyo, Laurent; Stolker, Tomas; Chiang, Eugene; de Boer, Jozua; Debes, John H.; Garufi, Antonio; Grady, Carol A.; Hines, Dean C.; Maire, Anne-Lise; Menard, Francoise; Millar-Blanchaer, Maxell A.; Perrin, Marshall D.; Poteet, Charles A.; Schneider, Glenn (IOP, 2020)
      More than a dozen young stars host spiral arms in their surrounding protoplanetary disks. The excitation mechanisms of such arms are under debate. The two leading hypotheses-companion-disk interaction and gravitational ...
    • 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 ...
    • The eccentric cavity, triple rings, two-armed spirals, and double clumps of the MWC 758 disk 
      Dong, Ruobing; Liu, Sheng Yuan; Eisner, Josh; Andrews, Sean; Fung, Jeffrey; Zhu, Zhaohuan; Chiang, Eugene; Hashimoto, Jun; Liu, Hauyu Baobab; Casassus Montero, Simón; Esposito, Thomas; Hasegawa, Yasuhiro; Muto, Takayuki; Pavlyuchenkov, Yaroslav; Wilner, David; Akiyama, Eiji; Tamura, Motohide; Wisniewski, John (IOP Publishing, 2018-06-20)
      Spatially resolved structures in protoplanetary disks hint at unseen planets. Previous imaging observations of the transitional disk around MWC 758 revealed an inner cavity, a ring-like outer disk, emission clumps, and ...
