Most stars are made of hydrogen and helium, with only tiny amounts of other elements. The ‘heavy metal stars’ are different – their atmospheres appear to be enriched in exotic heavy elements such as lead, zirconium and others. I will explain how the heavy metal stars differ from the norm, and what causes these elements to accumulate in their atmospheres.
Laua is from England and did her masters in astrophysics at the University of Birmingham, before moving to Keele to do a PhD on convection in massive stars. Now she lives in Armagh and works at the Observatory, researching stellar atmospheres.
