JERUSALEM, Sept. 4 (Xinhua) -- A new study has found that most massive stars in the early universe formed as binary systems, meaning they were born in pairs, similar to the way many massive stars form ...

But even the mass of a brown dwarf isn't enough to overcome the Coulomb barrier and start up stellar fusion. Fusion takes so much energy that some elements, up to the atomic mass of iron, are only ...

The stars were known to have heavy elements formed by the r-process in earlier generations of stars.

Elements heavier than iron, such as gold and uranium, are primarily formed through neutron capture processes, specifically the rapid neutron capture process (r-process). The r-process, unlike the ...

Chemistry in the first 50 million to 100 million years after the Big Bang may have been more active than we expected.

Astronomers have detected the first-ever signs of nuclear fission happening in stars, a discovery that sheds light on how elements heavier than those found naturally on Earth form in the cosmos ...

The first generations of stars formed from gas containing few or no elements heavier than helium (called 'metals' by astronomers). Star formation processes under these conditions would probably ...

The formation of the heavy elements Stars go through a series of fusion reactions in their interiors as they age. Through these reactions, elements from hydrogen to iron can be formed.

The scientists searched for evidence of these particularly ancient stars in the Large Magellanic Cloud and catalogued ten of them, first with the European Space Agency’s Gaia satellite and then with ...
