WebAug 11, 2024 · The known laws of physics suggest that by about 10 100 (the No. 1 followed by 100 zeros) years from now, star birth will cease, galaxies will go dark, and even black holes will evaporate through a process known as Hawking radiation, leaving little more than simple subatomic particles and energy. The expansion of space will cool that energy ... WebStars forge heavy elements by fusion in their cores. In a star of intermediate mass, these elements can mix into the star’s atmosphere and be spread into space through stellar winds.

The S-process is “slow” in a relative manner. It may take seconds to tens of thousands of years, but the key to differentiating is the length of time before additional neutron captures.

WebOct 14, 2009 · Second, most stars don't even fuse all the elements up to iron. Third, for the stars that do fuse elements up to iron, the heavy elements are almost always blown off in the ensuing supernova explosion, leaving a neutron star.

WebIf the star isn't large enough, nuclear fusion may stop, before the core of the star is fused to iron, since very high temperature (more than 2 billion Kelvin) and pressure are needed to fuse silicon to iron. This way the core may collapse earlier. The collapse releases energy responsible for much of the luminosity of the supernova.
