论文摘要
我们探索了一种新的场景,用于生产剥离的Envelope超新星祖细胞。在我们的情况下,剥离的envelope超新星是二进制的第二个超新星,其中二进制的信封在其红色超级阶段被第一个超级新星的影响删除。通过2D流体动力模拟,我们发现$ \ sim $ 50-90 $ \%$ \%$ \%$ $ \%$只要前苏佩诺诺娃的轨道分离为$ \ sillsim5 $倍$乘以恒星半径。重组能量在解除界面中起着重要作用,尤其是对于相对较高的质量系统($ \ gtrsim18m_ \ odot $)。我们预测,超过一半的未结合质量应以$ \ sim $ \ sim $ 10-100 $ 10-100%的距离分配给距离第二个超新星站点的单面外壳。我们讨论了已知的超新星残留物的可能应用,例如Cassiopeia A,RX J1713.7-3946,G11.2-0.3,并找到有希望的协议。预测的利率为$ \ sim $ 0.35-1 $ \%$ \%$ $ \%$。这种新场景可能是剥离式eNVELOPE或类型超新星子类的主要渠道,该类别缺乏Cassiopeia A.

We explore a new scenario for producing stripped-envelope supernova progenitors. In our scenario, the stripped-envelope supernova is the second supernova of the binary, in which the envelope of the secondary was removed during its red supergiant phase by the impact of the first supernova. Through 2D hydrodynamical simulations, we find that $\sim$50-90$\%$ of the envelope can be unbound as long as the pre-supernova orbital separation is $\lesssim5$ times the stellar radius. Recombination energy plays a significant role in the unbinding, especially for relatively high mass systems ($\gtrsim18M_\odot$). We predict that more than half of the unbound mass should be distributed as a one-sided shell at about $\sim$10-100pc away from the second supernova site. We discuss possible applications to known supernova remnants such as Cassiopeia A, RX J1713.7-3946, G11.2-0.3, and find promising agreements. The predicted rate is $\sim$0.35-1$\%$ of the core-collapse population. This new scenario could be a major channel for the subclass of stripped-envelope or type IIL supernovae that lack companion detections like Cassiopeia A.
