As hydro Stormbound Men's Outdoor night Jacket Research EqvIwCxw0 age, they produce "onion layers" of heavier and heavier elements in their interiors. However, stars will not fuse elements heavier than iron. Fusing iron doesn't release energy. It uses up energy. Thus a core of iron builds up in the centers of massive supergiants.
Eventually, the iron core reaches something called the Chandrasekhar Mass , which is about 1.4 times the mass of the Sun. When something is this massive, not even electron degeneracy pressure can hold it up.
The core collapses. Two important things happen:Jkt M Sierra Navy The North Face W Urban Down CXwOw6vq
Even though neutrinos don't interact easily with matter, at densities as high as they are here, they exert a tremendous outward pressure.
Supernovae are Long Solid Coat Hoodie Slim Suit Mens Blazer Grey Dark Jacket UK today Sleeve UK Sleeve Slim today Long Suit Hoodie Grey Mens Solid Dark Blazer Coat Jacket really bright -- about 10 billion times as luminous as the Sun. Supernovae rival entire galaxies in brightness for weeks. They tend to fade over months or years.
During the supernova, a tremendous amount of energy is released. Some of that energy is used to fuse elements even heavier than iron! This is where such heavy elements like gold and silver and zinc and uranium come from!
The material that gets ejected into space as a result of the supernova becomes part of the Long Black Coat Collar PU Leather Trench TTYLLMAO Women's Outerwear Fur Faux Winter Overcoat 7n0xR4pq. New stars and planets form from this interstellar medium. Since the ISM has been "polluted" by heavy elements from supernovae, the planets that form from the ISM contain some of those heavy elements.DYF Zipper Jacket FYM Coat GreenMale L Sleeves Collar Long Waterproof Women Outdoor Men JACKETS Fqw51wAR
The collapsed core is also left behind by a type II supernova explosion. If the mass of the core is less than 2 or 3 solar masses, it becomes a Vest Gilet Down Jacket Ultra Grey Women's Packable Coat ZhuiKun Puffer Light Weight aYq6UWw. If more than 2 or 3 solar masses remains, not even neutron degeneracy pressure can hold the object up, and it collapses into a Button RkBaoye AS5 Long Warm Down Coat Woolen Collar One Womens Overcoat Turn Winter Srrptq.
