Description
Title: Probing Massive Star Formation with (Sub-)Millimeter Observations
Speaker: Kai Yang
Abstract: Massive stars (> 8 solar mass) play a crucial role in shaping the energy dynamics of galaxies through their radiation, stellar winds, and supernova events. However, the formation of high-mass stars remains a mysterious process, being far less understood than it is for their low-mass counterparts.
The study of multi-scale structures in star-forming regions is rapidly expanding, providing new insights into the physical and chemical processes. Spectral line studies at (sub-)millimeter wavelengths over a wide range of physical scales serve as powerful probes to investigate these processes. In this talk, I will briefly introduce the current understanding of massive star formation and present recent progress on filaments, cosmic ray ionized rate, and outflow, with the observations of ALMA, NOEMA, SMA and the IRAM 30m telescope.
Bio: Kai Yang received his bachelor’s degree from Nanjing University and his Ph.D. from the University of Chinese Academy of Sciences (Shanghai Astronomical Observatory). He then continued as a postdoctoral researcher at Nanjing University. In 2024, He joined Shanghai Jiao Tong University as a postdoctoral fellow. His research focuses on massive star formation in our galaxy, interstellar medium, and observations at radio and (sub-)millimeter wavelengths.
