Type Ia Supernova.mp4
Summary: An animation depicting the formation of a Type Ia supernova, starting with a white dwarf accreting material from a companion star, leading to a catastrophic explosion.
This animation illustrates the stellar evolution leading to a Type Ia supernova. It begins with a binary star system where a larger, red giant-like star is gravitationally transferring hydrogen and helium to a smaller, denser companion – a white dwarf. This material forms an accretion disk around the white dwarf. As the white dwarf continuously accretes mass, its core pressure and temperature increase. When it reaches a critical mass, known as the Chandrasekhar limit (approximately 1.4 solar masses), a runaway thermonuclear fusion reaction ignites throughout its core, causing the white dwarf to violently explode as a Type Ia supernova, becoming incredibly luminous.
