长持续时间伽马射线暴（GRB）被认为是由大质量恒星的核心坍缩产生的，因此与超新星（SNe）有关。事实上，对于四对伽玛暴和SNe，光谱证实的连接已经牢固地建立起来。对于十几个伽玛暴的SN签名（“红色隆起”）已被检测到的余辉光变曲线。基于光谱学证实的四对GRB和SNe的联系，发现GRB的峰值光谱能量和SNe的峰值辐射光度之间存在紧密的相关性。最近发现的X射线闪光080109与SN 2008 D的正常核心塌陷有关，证实了这种关系，并扩展了GRB-SN的联系。简要回顾了GRB-SN连接的进展。
Long‐duration gamma‐ray bursts (GRBs) are believed to be produced by the core collapse of massive stars and hence to be connected with supernovae (SNe). Indeed, for four pairs of GRBs and SNe, spectroscopically confirmed connection has been firmly established. For more than a dozen of GRBs the SN signature (the ‘red bump’) has been detected in the afterglow lightcurves. Based on the four pairs of GRBs and SNe with spectroscopically confirmed connection a tight correlation was found between the peak spectral energy of GRBs and the peak bolometric luminosity of the underlying SNe. The recent discovery of X‐ray flash 080109 associated with a normal core‐collapse SN 2008D confirmed this relation and extended the GRB‐SN connection. Progress on the GRB‐SN connection is briefly reviewed.
