摘要
提出了将反弹冲击波在Ⅱ型超新星(SNⅡ)外星核区传输中的光裂解损耗看成为一个可调参量,用构造SNⅡ“瞬发爆炸模型”的方法研究前身星铁星核质量对SNⅡ瞬发爆炸的影响。并且给出了可发生SNⅡ瞬发爆炸的铁星核质量的范围。对WW(1993)SNⅡ前身星模型系列研究结果表明:由于铁星核质量过大,它们都不大可能发生瞬发爆炸。
Energy cost that bounce shock wave on its propagation through outer iron core must pay for dissociation of heavy nuclei is considered as an adjusted parameter. Based on this, the method of artificial prompt explosion model is proposed to research effects of iron core mass of SNⅡ on prompt explosion. Range of iron core mass of presuperonva models which can produce prompt explosion is estimatd. The preliminary investsgation shows that iron core mass of presupermova models of WW(1993) is too large to produce prompt explosion.
