Supernova <Linux FRESH>

This occurs in a double-star system where one star is a carbon-oxygen white dwarf. The white dwarf "steals" matter from its companion star. Once it reaches a critical mass (the Chandrasekhar limit), it triggers a runaway nuclear fusion reaction that completely obliterates the star.

This happens to massive stars—at least five to eight times the mass of our Sun. As the star runs out of nuclear fuel, its core becomes unstable. Gravity eventually wins the "tug-of-war" against outward pressure, causing the core to collapse in milliseconds. The outer layers then rebound off the dense core and explode outward into space. Scientific Significance Supernova

While there are several sub-categories, astronomers generally classify supernovas into two primary types based on what triggers the final collapse: This occurs in a double-star system where one

Beyond their visual spectacle, supernovas are essential to the evolution of the cosmos: What Is a Supernova? | NASA Space Place This happens to massive stars—at least five to
