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 ...

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 ...

A simulation of a rapidly accreting white dwarf showing a proposed site for the intermediate (i) process and the Summing NaI (SuN) detector. The research studied the 139Ba+n reaction, constrained by ...

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 ...

Researchers from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences and their collaborators have recently made great progress in the study of the stellar beta-decay rate of 59 Fe ...

The National Academies of Sciences, Engineering, and Medicine are private, nonprofit institutions that provide expert advice on some of the most pressing challenges facing the nation and world. Our ...

Abstract: Professor Hal describes the Big Bang, introduces us to the main actors who discovered the evidence for it and expands upon the evidence for it. He explains where the elements come from and ...

Walter Baade, at Palomar during the Second World War, observed that the halo of the great spiral Andromeda galaxy was dominated by red, metal-depleted stars, whereas its disk contained mainly blue, ...
