摘要
基于超新星前身型模型WS15 M⊙,详细计算了在一维球对称未旋转条件和旋转条件下的流体动力学时标和电子俘获时标,进行了比较,发现在形成激波前很短时间内电子俘获时标将小于流体动力学时标,这种差异在旋转的星体下更为明显.计算结果支持了新近提出一种超新星爆发图像,可能对超新星的爆发机制研究有新的影响.
Based on the presupernova WS15 M, the detailed calculations and compansons oi electron capture timescale and hydrodynamic timescale at one-dimension non-rotating and rotating case are done. The resuits show that the dectron capture timescales are shorter than hydrodynamic timescales in a short time before shock bounce. This difference becomes more obvious at rotating case. The conclusions support a new supernova mechanism, and may make .some new effects on the research of the explosion of supernova.
