高質量恆星形成:眾挑戰的一種修正觀點


Seminar:- High-mass Star Formation: a Revised View of the Challenges 
 
The speaker will review the state-of-the-art questions in forming the highest mass stars; radiation pressure, fragmentation and feedback. Next, he will present new ALMA and VLT adaptive optics data of G333.6-0.2, the most luminous star-forming core of the Milk-way disk, and demonstrate the effects of fragmentation, feedback, radiation pressure. The intense UV radiation from young O-stars have been theorised to ionise its own accretion flow, which is discovered for the first time from our data. The speaker will conclude with an emerging view of high-mass star formation scenario from these and other ALMA observations.
