Abstract:
To characterize the EOS of the dark energy based on SNe Ia Hubble diagrams requires to decrease the present dispersion in the SNIa calibration relation. Systematic effects, like extinction and evolution with redshift, may limit the precision by which SNe Ia could be used to measure Cosmology. Observations indicate that brighter SNe Ia occur only in systems with ongoing star formation and that the majority of SNe Ia comes from young progenitors. In this talk I will focus on the challenge to understand, from a theoretical point of view, the dispersion in the calibration relation and the link between SNIa progenitors and light curves.
