Supercomputer simulations identify stellar rotation as the mechanism driving chemical mixing in red giants, explaining long-observed surface composition changes during stellar evolution.

Low-energy nuclear fusion reactions can potentially provide clean energy. In stars, low-energy fusion reactions during the stages of carbon and oxygen burning are critical to stellar evolution. These ...

Astronomers using NASA’s Chandra X-ray Observatory have captured an unprecedented image of a stellar bubble surrounding a ...

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, ...

SN 2024abfl, a low-luminosity Type IIP supernova in the galaxy NGC 2146. This rare find is shedding new light on how stars ...
