Overview wording
[edit]Which is better:
A star of less than about 8 solar masses does not ordinarily undergo core collapse, other than in the event of accretion by a white dwarf. Once fusion ceases it gradually cools. Some stars of 4-8 solar masses explode without prior collapse and leaving no remnant. The two explosion processes are known respectively as carbon detonation and carbon deflagration, the former giving rise to core collapse and a type 1a supernova and the latter a carbon deflagration supernova without core collapse. A star of less than about 8 solar masses does not ordinarily undergo core collapse. Once fusion ceases the resulting white dwarf gradually cools. The exception is when accretion takes place and the white dwarf gains additional mass from an external object such as a companion star. The added mass can cause reignition and carbon detonation, and can cause core collapse and a type 1a supernova. Some stars of 4-8 solar masses explode without prior collapse and leaving no remnant, known as carbon deflagration giving rise to a carbon deflagration supernova, but without core collapse.
