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. WebNov 3, 2000 · Stars More Massive Than the Sun When the core runs out of hydrogen, these stars fuse helium into carbon just like the sun. However, after the helium is gone, their mass is enough to fuse carbon into heavier elements such as oxygen, neon, silicon, magnesium, sulfur and iron. Once the core has turned to iron, it can burn no longer. WebInterior Structure of a Massive Star Just before It Exhausts Its Nuclear Fuel: High-mass stars can fuse elements heavier than carbon.

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. 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 ...
