This fusion reaction releases a tremendous amount of energy in a very short time, causing the accumulated surface layer to explode violently away from the dwarf. A nova involves the explosion of only the accumulated surface layer of a white dwarf; the dwarf itself survives the event and can continue to accrete material, potentially exploding again in the future.
Nova vs. Regular Star: Understanding the Difference
Understanding the Stellar Foundation Before examining the explosion, it is essential to establish that the subject is fundamentally a star. A nova is a specific and dramatic event occurring on the surface of a white dwarf star, which is the dense, collapsed core of a once-normal star.
To understand this phenomenon, one must first grasp the nature of the star itself before exploring the violent explosion that defines the nova. Stars with masses up to about eight times that of our Sun do not end in supernovae but instead shed their outer layers gently, leaving behind a hot, dense core known as a white dwarf.
Nova vs Regular Star: Understanding the Difference
Through nuclear fusion in its core, it converts hydrogen into helium, releasing enormous energy that creates outward pressure, balancing the inward pull of gravity and providing the light and heat we observe. This stable phase can last for millions to billions of years, depending on the star's mass.
