    • Huang, Jane; Andrews, Sean M.; Dullemond, Cornelis P.; Öberg, Karin I.; Qi, Chunhua; Zhu, Zhaohuan; Birnstiel, Tilman; Carpenter, John M.; Isella, Andrea; Macías, Enrique; McClure, Melissa K.; Pérez Muñoz, Laura; Teague, Richard; Wilner, David J.; Zhang, Shangjia (IOP Publishing, 2020)
      The protoplanetary disk around the T Tauri star GM Aur was one of the first hypothesized to be in the midst of being cleared out by a forming planet. As a result, GM Aur has had an outsized influence on our understanding ...
    • 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 ...
    • Huang, Jane; Andrews, Sean M.; Cleeves, L. Ilsedore; Oberg, Karin I.; Wilner, David J.; Bai, Xuenin; Birnstiel, Til; Carpenter, John; Hughes, A. Meredith; Isella, Andrea; Pérez Muñoz, Laura; Ricci, Luca; Zhu, Zhaohuan (IOP Publishing Ltd, 2018)
      We analyze high angular resolution ALMA observations of the TW Hya disk to place constraints on the CO and dust properties. We present new, sensitive observations of the (CO)-C-12 J = 3 - 2 line at a spatial resolution of ...

Meredith; Ricci, Luca; Weaver, Erik; Wilner, David J. (IOP, 2020)
    • Cieza González, Lucas; Casassus Montero, Simón; Tobin, John; Bos, Steven; Williams, Jonathan; Pérez, Sebastián; Zhu, Zhaohuan; Canovas, Héctor; Dunham, Michael; Hales, Antonio; Prieto, José; Principe, David; Schreiber, Matthias; Ruiz Rodríguez, Dary; Zurlo, Alice (Nature Publishing Group, 2016)
      A snow-line is the region of a protoplanetary disk at which a major volatile, such as water or carbon monoxide, reaches its condensation temperature. Snow-lines play a crucial role in disk evolution by promoting the rapid ...
    • Huang, Jane; Andrews, Sean M.; Oberg, Karin I.; Ansdell, Megan; Benisty, Myriam; Carpenter, John M.; Isella, Andrea; Pérez Muñoz, Laura; Ricci, Luca; Williams, Jonathan P.; Wilner, David J.; Zhu, Zhaohuan (IOP, 2020)
      While protoplanetary disks often appear to be compact and well organized in millimeter continuum emission, CO spectral line observations are increasingly revealing complex behavior at large distances from the host star. ...
    • 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 ...
    • 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, ...
    • 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 ...
    • 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 ...

      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 ...
