    • An asymmetric explosion as the origin of spectral evolution diversity in type Ia supernovae 
      Maeda, K.; Benetti, S.; Stritzinger, M.; Röpke, F. K.; Folatelli, Gastón; Sollerman, J.; Taubenberger, S.; Nomoto, K.; Leloudas, G.; Hamuy Wackenhut, Mario; Tanaka, M.; Mazzali, Paolo; Elias Rosa, N. (2010-07-01)
