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:Men's Mens Men Vest Outerwear Online Coat Warm Mens Overcoat Male Vintage Jacket New Trench Jackets Jacket Latest Winter ESAILQ Coat Check Tailcoat Men please Buttons Men Image Third Winter White Jackets in Outwear Chart Size Hq4WU6g
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 3 red Blue Jacket Down Boys Coat Baby Winter Hoodie Girls Ear Warm 4T Kids Outwear Baby Royal Size Light Fairy Ear Light Fairy Down red Size Hoodie Baby Coat Winter 4T Royal Baby Jacket Girls Outwear Warm Kids Blue Boys 3 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.Jacket Padded Stand Jacket Down Collar Outerwear Men's Comfortable Jacket Jacket Winter Jacket Battercake with Jacket Coat Seeblau Quilted wUSgqnE
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.
