The simmering phase of Type Ia SNe

Venerdì 17 aprile alle ore 14:30, il Dr. Luciano Piersanti dell’INAF-Osservatorio Astronomico d’Abruzzo, ha tenuto il web-seminar dal titolo “The simmering phase of Type Ia SNe“.

Web-seminar ad accesso riservato.



Type Ia Supernovae represent very precise standardized distance indicators on cosmological distances, even if the origin of their diversity has not been explained so far. In this talk I will review the potential effects of the stellar progenitor initial metallicity Z on the physical and chemical properties of the exploding WD. I will analyze the interplay of convection and URCA processing during the simmering phase and I will discuss the limits of the current generation theoretical models.
