摘　　要：Type Ia supernovae(SNe Ia)can be used as the standard candle to determine the cosmological distances because they are thought to have a uniform fuel amount.Recent observations of several overluminous SNe IaType Ia supernovae （SNe Ia）can be used as the standard candle to determine the cosmological distances because they are thought to have a uniform fuel amount. Recent observations of several overluminous SNe Ia suggest that the white dwarf masses at supernova explosion may significantly exceed the canonical Chandrasekhar mass limit. These massive white dwarfs may be supported by rapid differential rotation.
