2009ApJ...705L.138P EC-SNe from Super-Asymptotic Giant Branch Progenitors: Theoretical Models Versus Observations Pumo, M. L.; Turatto, M.; Botticella, M. T.; Pastorello, A.; Valenti, S.; Zampieri, L.; Benetti, S.; Cappellaro, E.; Patat, F. Abstract. Using a parametric approach, we determine the configuration of super-asymptotic giant branch (super-AGB) stars at the explosion as a function of the initial mass and metallicity, in order to verify if the electron-capture supernova (EC-SN) scenario involving a super-AGB star is compatible with the observations regarding SN2008ha and SN2008S. The results show that both the supernovae (SNe) can be explained in terms of EC-SNe from super-AGB progenitors having a different configuration at the collapse. The impact of these results on the interpretation of other subluminous SNe is also discussed. Key words: stars: AGB and post-AGB, stars: evolution, supernovae: general, supernovae: individual: SN2008ha SN2008S
