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.
Massive stars in metal-poor galaxies often have close partners, just like the massive stars in our metal-rich Milky Way. This was discovered by an international team of 70 astronomers led by scientists from Belgium, the Netherlands, ...

Astronomers from Argentina and Spain have performed near-infrared observations of a massive young stellar object known as MYSO G29.862−0.0044. The observational campaign sheds more light on the nature of this object and ...
The size of our universe and the bodies within it is incomprehensible to us lowly humans. The sun has a mass that is more than 330,000 times that of our Earth, and yet there are stars in the universe that completely dwarf ...

An international team of astronomers has employed NASA's Chandra X-ray observatory to perform the most detailed study of a supergiant star known as Wd1-9, which yielded important insights into the properties and nature of ...
Stars of all ages and masses emit electromagnetic energy in different ways, and these emissions attract the attention of astronomers. Each of these emissions is a clue to how stars form, evolve, and even die. Young stars ...

Very massive stars (VMSs) have had a massive impact on the formation of our universe. However, there aren't very many of them, with only around 20 known specimens in the Milky Way and Large Magellanic Cloud. Even observing ...
