| Abstract: |
At redshift z ≥ 5 supernovae are the only known dust sources with evolutionary timescales shorter than the Hubble time. We extend the model of dust formation in the ejecta of Type II SNe by Todini & Ferrara (2001) to investigate the same process in pair-instability supernovae (SNγγ), which are though to arise from the explosion of the first, metal free, very massive (140-260 MSolar) stars in the Universe. The cosmological implications of high-z dust formation are discussed. |
