Abstract
I will review the state-of-the-art questions in forming the highest mass stars; radiation pressure, fragmentation and feedback. Next, I 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. I will conclude with an emerging view of high-mass star formation scenario from these and other ALMA observations.
Coffee and tea will be served 20 minutes prior to the seminar.
Anyone interested is welcome to attend.
