When the pressure reaches a critical point, nuclear fusion is triggered in a thin shell around the core. This stellar remnant is roughly the size of Earth but contains the mass of the original star, making it incredibly dense.
Understanding the Stellar Core and Nuclear Fusion Process
Astronomers observe the initial optical brightening, which can make the star suddenly visible in the night sky, sometimes outshining its entire host galaxy for a brief period. Understanding the Stellar Foundation Before examining the explosion, it is essential to establish that the subject is fundamentally a star.
This explosion is what we observe as the sudden brightening of a nova. This stable phase can last for millions to billions of years, depending on the star's mass.

While both are stellar explosions, their origins and outcomes are entirely different. In binary star systems, where two stars orbit a common center of mass, this white dwarf can act as a cosmic vacuum cleaner, pulling material from its companion star.
