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 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 ...

Galactic chemical evolution (GCE) describes the changing composition of galaxies over cosmic time as successive generations of stars forge new elements and redistribute them into the interstellar ...

Astronomers like to say we are the byproducts of stars, stellar furnaces that long ago fused hydrogen and helium into the elements needed for life through the process of stellar nucleosynthesis. But ...

When the renowned cosmologist Carl Sagan declared that "we are made of starstuff," he wasn't speaking metaphorically. As Sagan said in the TV series "Cosmos," many of the elements in our bodies - "the ...

Stellar nucleosynthesis is the research area concerned with the nuclear processes by which chemical elements are formed and transformed within stars and related astrophysical environments. It ...

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 ...

An international team of astronomers reports the discovery of a star, HE1327-2326, which sets a new record for being the most heavy element-deficient star ever found. Its chemical composition, as ...

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 ...

A team of international researchers went back to the formation of the solar system 4.6 billion years ago to gain new insights into the cosmic origin of the heaviest elements on the periodic table. Led ...

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 ...
