Stellar evolution as a research area investigates the physical processes governing the formation, structural changes, and end states of stars across cosmic time, using stellar structure theory, nuclear astrophysics, hydrodynamics, and radiative transfer. It encompasses modeling of protostellar collapse, main-sequence hydrogen burning, post–main-sequence shell burning, and advanced nucleosynthesis up to core collapse or thermonuclear disruption, as well as mass loss, rotation, magnetic fields, and binary interactions. The field integrates observations (e.g., HR diagrams, asteroseismology, stellar populations) with numerical simulations to constrain stellar lifetimes, remnant formation (white dwarfs, neutron stars, black holes), and the chemical and energetic feedback of stars into galaxies.
Astronomers have watched a dying star fail to explode as a supernova, instead collapsing into a black hole. The remarkable sighting is the most complete observational record ever made of a star's transformation into a black ...

Aging stars can completely destroy their planets. When a star reaches the end of its life on the main sequence, it goes through dramatic changes. And those changes don't just dictate the star's fate; they can also dictate ...

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 ...
