If the core of the collapsing star is between about 1 and 3 solar masses, these newly …
WebA neutron star forms when a main sequence star with between about eight and 20 times the Sun’s mass runs out of hydrogen in its core. (Heavier stars produce stellar-mass black holes.) The star starts fusing helium to carbon, like lower-mass stars. WebOct 21, 2024 · The neutrinos can zip out of the star freely, but the neutrons are crushed closer together until they exert their own gravity-fighting degeneracy pressure, creating a …
WebDec 8, 2024 · Now, scientists are learning how most of the Universe’s heavy metals, like silver, gold, platinum and uranium, are generated. Without metals, life (as we know it) can not exist.
