When, where and how were the heavy elements produced in the young Universe? Present theories say that it mainly happened in supernova explosions, but only accurate observations of very old stars can show whether this is true or not. Drs. Monique and Fran90is Spite from the Paris Observatory in Meudon recently started a study of very metal-deficient stars in the Galaxy to see if there are minor differences in the abundances of the individual metals, as predicted by theory. Here they inform us about the reasons for their observations and give some of the first results.
