WebJul 8, 2024 · Neutron stars and black holes are born from dying stars. As a star runs out of hydrogen to fuse into helium, it becomes unstable and collapses. If the star is large enough, it will go supernova, and the core will become a neutron star. If the star is even larger, the core will become a black hole. WebStars can easily fuse atoms to give of heat and radiation. But at Wikipedia it said that only sub-iron atoms give of energy when fused and take energy when split, and post-iron atoms is the exact opposite. So, if enough heavy elements got together could a "reverse star" be made in which it gives of light and heat through means of fission?

Weba) The outer layers of the star are no longer gravitationally attracted to the core. b) Hydrogen fusion in a shell outside the core generates enough thermal pressure to push the upper layers outward. c) Helium fusion in the core generates enough thermal pressure to push the upper layers outward. WebAnswer (1 of 7): Humans have defined the term “star” such that fusion as a necessary requirement for qualifying as one.

WebNov 6, 2024 · Stars don't fuse helium to beryllium except as a very, very short intermediate step toward carbon. Helium-helium fusion to form beryllium is endothermic: It consumes energy. To make matters worse, the beryllium-8 that results has an extremely short half-life, less than 10 − 16 seconds. WebApr 30, 2024 · The fusion process forces hydrogen atoms together, transforming them into heavier elements such as helium, carbon and oxygen.

WebHaving achieved iron, the star has wrung all the energy it can out of nuclear fusion - fusion reactions that form elements heavier than iron actually consume energy rather than produce it. The star no longer has any way to support its own mass, and the iron core collapses. In just a matter of seconds the core shrinks from roughly 5000 miles ... WebMar 8, 2024 · The most common elements, like carbon and nitrogen, are created in the cores of most stars, fused from lighter elements like hydrogen and helium. The heaviest elements, like iron, however, are only formed in the massive stars which end their lives in supernova explosions.

WebAlso, it is possible for heavier nuclei to be fused in stars that result in more energy being produced than is used, but these are unstable isotopes and they decay quickly. So, more accurately, iron is the heaviest element produced in stellar nucleosynthesis in any significant quantity that produces more energy in fusion than the fusion consumes.
