本文对超超新星（HNe）和伽玛射线暴（GRB）的速率进行了比较。在相当大的不确定性，估计是相当可比的，并给出了银河系的速度为10-6至10-5年-1的两个事件。这些速率比核心坍缩超新星的速率低几个数量级，这表明导致HN/GRB的演化需要特殊的环境，很可能是由于双星相互作用。各种可能的二进制通道进行了讨论，它表明，这些是一般兼容的推断率。
A critical comparison of estimates for the rates of hypernovae (HNe) and gamma-ray bursts (GRBs) is presented. Within the substantial uncertainties, the estimates are shown to be quite comparable and give a galactic rate of 10-6 to 10-5 yr-1 for both events. These rates are several orders of magnitude lower than the rate of core-collapse supernovae, suggesting that the evolution leading to an HN/GRB requires special circumstances, very likely due to binary interactions. Various possible binary channels are discussed, and it is shown that these are generally compatible with the inferred rates.
