Summary

Like houses in an industrial area, the stars in a globular cluster are polluted by the exhausts from nearby chemical plants. In a paper to appear in Astronomy and Astrophysics, Italian astronomers report that sun-sized stars in a globular cluster known as NGC 6752 contain heavy elements that cannot be manufactured in stars that small. The astronomers think the stars acquired the material from now-defunct larger stars--a type of recycling previously seen only in a few binary star systems.
