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.

孤独的剥离包络超新星祖先的形成途径：对仙后座 A 的影响

我们探索了一种产生剥离包络超新星祖先的新方案。在我们的场景中，剥离包络的超新星是双星的第二颗超新星，其中次级的包络在其红超巨星阶段因第一颗超新星的撞击而被移除。通过二维流体动力学模拟，我们发现只要超新星前的轨道间隔是恒星半径的 $\lesssim5$ 倍，包络的 $\sim$50-90$\%$ 就可以不受约束。重组能在解结合中起着重要作用，特别是对于质量相对较高的系统（$\gtrsim18M_\odot$）。我们预测，超过一半的未结合质量应该以单面壳的形式分布，距离第二个超新星地点约 $\sim$10-100pc。我们讨论了已知超新星遗迹的可能应用，如仙后座 A、RX J1713。7-3946，G11.2-0.3，并找到有希望的协议。预测的比率是核心塌陷人口的 $\sim$0.35-1$\%$。这种新场景可能是像仙后座 A 那样缺乏伴星探测的剥离包络或 IIL 型超新星子类的主要通道。
