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

The characteristic luminosity of the kilonova is approximately equal to the radioactive heating rate at this escape timescale: A larger ejecta mass produces a brighter and longer-lasting kilonova; a ...

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 ...

It seems so simple: where do the elements come from? We can study the individual constituents that make up the classical elements of the periodic table, and we can certainly do cool things with those ...

For the first time, astronomers have definitively ID’d a specific heavy element forged by a neutron star merger. Theories of physics have long predicted that about half of the universe’s heavy ...

How are chemical elements produced in our Universe? Where do heavy elements like gold and uranium come from? Using computer simulations, a research team shows that the synthesis of heavy elements is ...
