Multi-wavelength Observational Study of High-mass Star Formation in the Milky Way
In the last decade, improved sensitivities and angular resolutions have unveiled more details about the formative processes of the massive stars. Gradually, we are narrowing down to two theories of high-mass star formations - core accretion and competitive accretion theories. Among the questions that recent observations have answered includes ‘do massive stars have disks?’, if so, 'are their disks Keplerian?’. How do they grow into tremendously massive object? In my talk, I will use multi-wavelength observational results to logical show what we currently know about how massive stars form. It is crucial that we understand these processes because massive stars are the source of heavy elements in galaxies and play key role in the evolution of their host galaxies.
