The core contracts into a dense white dwarf. When the core accumulates enough iron, it collapses under gravity within seconds.
White Dwarf Explosion: Understanding the Supernova Trigger
Legacy and Cosmic Impact The remnants of a supernova enrich the interstellar medium with materials necessary for planet and life formation. The shockwaves can trigger the formation of new stars in nearby nebulae.
The initial flash can rival the brightness of a galaxy. Understanding these events is essential for modeling galactic evolution and the potential for life-supporting planets in the cosmos.
White Dwarf Explosion: Core Collapse and Thermonuclear Trigger
Type Trigger Progenitor Star Type Ia Thermonuclear explosion of a white dwarf White dwarf in a binary system Core-Collapse Core implosion due to iron accumulation Massive star (8+ solar masses). A supernova represents the spectacular explosion of a star, marking one of the most energetic events in the universe.
