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.
Astronomers have strengthened long-standing predictions that massive runaway stars could have originated in binary pairs, and were dramatically ejected into space when their companion stars underwent supernova explosions. ...
Using the James Webb Space Telescope (JWST), astronomers have discovered a new dwarf galaxy, which received designation CAPERS-39810. Further investigation of CAPERS-39810 revealed that it is an extremely metal-poor galaxy. ...
Researchers from the Institute of Cosmos Sciences of the University of Barcelona (ICCUB) and the Institute of Space Studies of Catalonia (IEEC), in collaboration with the Institute of Astrophysics of the Canary Islands (IAC), ...

In our galaxy, a supernova explodes about once or twice each century. But historical astronomical records show that the last Milky Way core-collapse supernova seen by humans was about 1,000 years ago. That means we've missed ...

Betelgeuse is the star that everybody can't wait to see blow up, preferably sooner rather than later. That's because it's a red supergiant on the verge of becoming a supernova and there hasn't been one explode this close ...

What we know of the birth of a black hole has traditionally aligned with our perception of black holes themselves: dark, mysterious, and eerily quiet, despite their mass and influence. Stellar-mass black holes are born from ...
