    • Environment and Protostellar Evolution 
      Zhang, Yichen; Tan, Jonathan C. (IOP Publishing, 2015)
      Even today in our Galaxy, stars form from gas cores in a variety of environments, which may affect the properties of the resulting star and planetary systems. Here, we study the role of pressure, parameterized via ambient ...
    • Massive protostars in a protocluster-a multi-scale ALMA view of G35.20-0.74N 
      Zhang, Yichen; Tanaka, Kei E. I.; Tan, Jonathan C.; Yang, Yao-Lun; Greco, Eva; Beltrán, María T.; Sakai, Nami; De Buizer, James M.; Rosero, Viviana; Fedrian, Rubén; Garay Brignardello, Guido Alejandro (IOP, 2022)
      We present a detailed study of the massive star-forming region G35.2-0.74N with Atacama Large Millimeter/submillimeter Array (ALMA) 1.3 mm multi-configuration observations. At 0.'' 2 (440 au) resolution, the continuum ...
    • Outflow-confined H II regions. I. First signposts of massive star formation 
      Tanaka, Kei; Tan, Jonathan; Zhang, Yichen (IOP PUBLISHING, 2016)
      We present an evolutionary sequence of models of the photoionized disk-wind outflow around forming massive stars based on the Core Accretion model. The outflow is expected to be the first structure to be ionized by the ...
