Iron in binary stars reflects Galaxy’s chemical evolution
The dance that binary stars do around each other offers new clues to the chemical evolution of our Galaxy, the Milky Way – so says a current research study. For the first time, researchers have identified the link between the orbiting times of certain binary stars and the amount of iron in in their interiors. Binary stars are systems containing two stars that orbit each other thanks to their mutua
