| Abstract: | A new interpretation is given to the low metallicity peak of the bimodal metallicity histogram of galactic globular clusters.
It is proposed that these globular clusters are primordial,i.e., formed out of big-bang matter. Their nonvanishing metallicity is attributed to pollution by supermassive stars like R 136a.
The first stellar generation is formed out of the ‘dirty’ primordial matter. |
