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 ...

For decades, astronomers have wondered what the very first stars in the universe were like. These stars formed new chemical ...

Ultimately, astronomers are undecided about how such elements are formed—in supernova explosions, which are relatively common, or in something rare and exotic, such as the merger of neutron stars.

Scientists find one of the most ancient stars that formed in another galaxy Stars from the Large Magellanic Cloud reveal new hints about how the universe got its elements Date: March 21, 2024 ...

Astronomers studying how elements heavier than iron were produced in the early Milky Way have identified a distinct series of epochs of galaxy-wide chemical formation. This evolutionary timeline ...

Stars formed of elements other than hydrogen would have different masses and evolutionary histories than normal hydrogen-rich stars.

How the first stars formed from dust and gas has been a burning question for years, but a state-of-the-art computer simulation now offers the most detailed picture yet of how these first stars in ...

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 ...

For decades, astronomers have wondered what the very first stars in the universe were like. These stars formed new chemical ...

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 ...
