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.
Star clusters are of great importance in any galaxy: they are the birthplace of new stars, often containing massive stars of 10 solar masses or more. Such massive stars often drive powerful winds; the combined action of all ...

Electron-capture supernovae (ECSNe) are stellar explosions that occur in stars with initial masses around 8–10 times that of the sun. These stars develop oxygen-neon-magnesium cores, which become unstable when electrons are ...
Betelgeuse, the brilliant red star marking Orion's shoulder, has long been suspected of harboring a secret. I have to confess, Betelgeuse holds a special place in my heart as the first star I ever looked at through a telescope ...
