Stars with not less than 9 M☉ (potentially just as much as twelve M☉[116]) evolve in a posh style, progressively burning heavier things at hotter temperatures inside their cores.
All Wolf–Rayet stars finish their life from your Wolf–Rayet period in one million many years or so, but again it can be hard to identify the ones that are closest to Main collapse. A person course that is expected to get no various thousand many years ahead of exploding are definitely the WO Wolf–Rayet stars, which can be regarded to own fatigued their Main helium.[236] Only 8 of them are recognised, and only four of those are while in the Milky Way.[237]
