Resum
The efficient use of Type Ia supernovae (SNIa) for cosmological studies requires knowledge of any parameter that can affect their luminosity in either systematic or statistical ways. Observational samples of SNIa commonly use the metallicity of the host galaxy, Zhost, as an estimator of the supernova progenitor metallicity, ZIa, that is one of the primary factors affecting SNIa magnitude. Here, we present a theoretical study of the relationship between ZIa and Zhost. We follow the chemical evolu...
