The study of stellar astrophysics and galactic structure investigates the life cycles of stars and the organisation of galaxies. At its core, the field explores how stellar evolution, from the ...

98.5% of the Sun is made up of two light chemical elements, hydrogen and helium, while the remaining 1.5% consists of other heavier elements such as carbon, oxygen, and iron. The abundance of these ...

Scientists have identified a never-before-seen supernova, SN2021yfj, which exploded after losing nearly all of its outer layers. Instead of light elements, it revealed silicon and sulfur from deep ...

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 ...
