Massive stars as a research area encompasses the theoretical, observational, and computational study of stars with initial masses typically ≥8–10 solar masses, focusing on their formation, internal structure, evolution, feedback, and endpoints. This field investigates radiative and mechanical feedback on the interstellar medium, nucleosynthesis and chemical enrichment, stellar winds, rotation, binarity, and magnetic fields, as well as the progenitors of core-collapse supernovae, gamma-ray bursts, and compact remnants. Research integrates multiwavelength observations, stellar evolution and hydrodynamic simulations, and population synthesis to constrain mass loss, convection, mixing processes, and the role of massive stars in galaxy evolution and cosmology.
