标题： Attributing the point symmetric structure of core-collapse supernova remnant N132D to the jittering jets explosion mechanism

摘要： 我在核心坍缩超新星（CCSN）遗迹（CCSNR）N132D中识别出一种点对称形态，由两条对称轴组成：短对称轴从西北耳延伸，并穿过另一侧铁丰富发射的中心，第二条对称轴沿着N132D的长维度，并与中心富氧气体向东北方向的延伸一致。 换句话说，CCSNR N132D外区的点对称性与中心附近富氧气体的点对称性相关。 周围的气体无法塑造内部富氧物质，这意味着点对称形态是爆炸机制的属性，正如抖动喷流爆炸机制（JJEM）所预测的那样。 已知富氧物质呈环状结构。 根据JJEM，一对能量较高的相反喷流，大致垂直于环的平面，塑造了该环；这对喷流沿短对称轴。 另一对能量较高的喷流，垂直于第一对，塑造了CCSNR N132D的伸长且大尺度结构。 我讨论了JJEM如何解释两对相互垂直的喷流以及每对中不相等的喷流。 CCSNR N132D是第十五个被识别出具有归因于JJEM的点对称形态的CCSNR。 由于中微子驱动机制无法解释此类形态，这项研究进一步加强了JJEM是CCSNe主要爆炸机制的主张。 显示英文摘要

摘要： I identified a point-symmetric morphology in the core-collapse supernova (CCSN) remnant (CCSNR) N132D, composed of two symmetry axes: the short symmetry axis extending from the northwest ear and through the center of the iron-rich emission on the other side, and the second along the long dimension of N132D and coincides with the extension of the central oxygen-rich gas to the northeast. Namely, the point-symmetry of the outer zones of CCSNR N132D correlates with that of the oxygen-rich gas near the center. The surrounding gas cannot shape the inner oxygen-rich material, implying that the point-symmetric morphology is a property of the explosion mechanism, as predicted by the jittering jets explosion mechanism (JJEM). The oxygen-rich material is known to be in a torus. According to the JJEM, an energetic pair of opposite jets, more or less perpendicular to the plane of the torus, has shaped the torus; this pair is along the short symmetry axis. Another energetic pair, perpendicular to the first one, shaped the elongated, large-scale structure of CCSNR N132D. I discuss how the JJEM accounts for two perpendicular pairs of jets and the unequal jets in each pair. CCSNR N132D is the fifteenth CCSNR with an identified point-symmetric morphology attributed to the JJEM. Because the neutrino-driven mechanism cannot explain such morphologies, this study further strengthens the claim that the JJEM is the primary explosion mechanism of CCSNe.
