Onion-like layers in the core of an enormous, developed star just ahead of core collapse In the course of their helium-burning period, a star of in excess of nine solar masses expands to type 1st a blue supergiant then a crimson supergiant. Notably substantial stars (exceeding 40 solar masses, like Alnilam, the central blue supergiant of Orion's Belt)[ninety two] will not turn into purple supergiants resulting from significant mass reduction.

Betelgeuse as observed by ALMA. This is certainly The 1st time that ALMA has noticed the area of the star and resulted in the very best-resolution picture of Betelgeuse out there. As stars of a minimum of 0.4 M☉[86] exhaust the supply of hydrogen at their core, they start to fuse hydrogen inside a shell encompassing the helium core. The outer levels of your star broaden and cool significantly as they transition right into a pink huge.
