How are heavy elements formed in the universe? Extremely neutron-rich atomic nuclei and their beta-decay rates play an important role in this process. Until now, it has been very difficult to ...

Deep observations of two X-ray bright clusters of galaxies with ESA’s XMM-Newton satellite allowed a group of international astronomers to measure their chemical composition with an unprecedented ...
The slow neutron-capture process (the s-process) is one of the nucleosynthesis processes that occurs in stars. It results in about half of the elements heavier than iron in the universe. Two important ...

Violent explosions of massive, magnetized stars may forge most of the universe’s heavy elements, such as silver and uranium. The ancient star’s elements aren’t from the remnants of a neutron star ...
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 ...
COLLEGE PARK, Md. — Using NASA’s Spitzer Telescope, an international research team has found evidence that some stars in the center of the Milky Way galaxy have both carbon and oxygen in the dust that ...
