    • A Photoionized Accretion Disk around a Young High-mass Star 
      Guzmán, Andres E.; Sanhueza, Patricio; Zapata, Luis; Garay Brignardello, Guido; Rodríguez, Luis Felipe (IOP, 2020)
      We present high spatial resolution (52 au) observations of the high-mass young stellar object (HMYSO) G345.4938+01.4677 made using the Atacama Large Millimeter/submillimeter Array. This O-type HMYSO is located at 2.38 kpc ...

R.; Walsh, Catherine; Wilner, David J.; Zhang, Ke (IOP, 2021)
      The Molecules with ALMA at Planet-forming Scales (MAPS) Large Program provides a unique opportunity to study the vertical distribution of gas, chemistry, and temperature in the protoplanetary disks around IM Lup, GM Aur, ...
    • Resolved carbon monoxide observations of protoplanetary discs in ophiuchus 
      Antilén Romero, Juanita Andrea (Universidad de Chile, 2022)
      The $^{12}$CO rotational lines in protoplanetary discs are good tracers of the total spatial extension of the gas component and potentially planet-disc interactions. This work analyses ALMA long-baseline observations of ...
