An international research team has recently developed a new proton capture reaction rate of copper-57 for the extreme astrophysical environment at the surface of neutron stars. The researchers found ...

Stellar nucleosynthesis is the creation (nucleosynthesis) of chemical elements by nuclear fusion reactions within stars. Stellar nucleosynthesis has occurred since the original creation of hydrogen, ...

In a study published in The Astrophysical Journal, scientists have proposed the features of rapid neutron capture process (r-process) nucleosynthesis in a novel scenario, common envelope jet ...

In science, you don't have to get everything right in order to get the most incredible things correct. Sometimes good ideas emerge from a failed paradigm. An excellent example of both is the ...

Stellar nucleosynthesis is the process by which stars forge elements inside their cores. The only element not formed in this way is hydrogen, the most abundant and lightest element in the universe: it ...

On a typical day at the world's biggest laser you can find scientists casually making star-like conditions using 192 high-powered lasers. Stars in the universe are formed through a process called ...

Measurements of the amount of lithium in the universe combined with precision data from the cosmic microwave background are challenging our understanding both of stellar astrophysics and possibly even ...

The Big Bang may have not been alone. The appearance of all the particles and radiation in the universe may have been joined by another Big Bang that flooded our universe with dark matter particles.

Stellar nucleosynthesis is the collective term for the nuclear reactions taking place in stars to build the nuclei of the heavier elements. The processes involved began to be understood early in the ...
