Abstract：

Massive stars are fundamental drivers of galactic evolution, exerting powerful feedback on their surroundings and shaping the ecology of their host galaxies. Over the past decade, high-resolution observations and state-of-the-art theoretical modeling have significantly advanced our understanding of their formation processes. In this talk, I will present recent theoretical and observational studies of massive star formation in both Galactic and low-metallicity environments. I will specifically discuss three key topics: (1) whether and how feedback regulates accretion onto very massive protostars; (2) dust evolution and gas chemistry in hot disks around massive protostars; and (3) new findings on massive protostars in low-metallicity environments such as the Magellanic Clouds, highlighting the potential diversity of star formation processes across different galactic contexts.
