论文摘要
脉冲配对超新星（PPISN）从质量$ \ sim 80 $ -140 $ m _ {\ odot} $的巨大恒星演变，该恒星在核心燃烧的液压燃烧后会发展出电子 - 素的配对稳定性。在[Leung等人，APJ 887，72（2019）]（论文I）中，我们检查了这类恒星的进化轨道和脉动质量损失历史。在本文中，我们分析了热力学史，以探索ppisne的中微子可观察到。我们在脉动过程中计算中微子光曲线和光谱。我们研究这些恒星的详细中微子发射谱。然后，我们估计不同陆地中微子检测器（包括Kamland和Super-Kamiokande）的预期中微子检测数。最后，我们将PPISN的中微子模式与基于规范10 KT检测器的其他类型的超新星进行了比较。预测的中微子信号可以为望远镜提供早期光学信号的预警。讨论了中微子物理学对预期检测的影响。
A Pulsational Pair-instability supernova (PPISN) evolves from a massive star with a mass $\sim 80$ -- 140 $M_{\odot}$ which develops the electron-positron pair-instability after the hydrostatic He-burning in the core has finished. In [Leung et al., ApJ 887, 72 (2019)] (Paper I) we examined the evolutionary tracks and the pulsational mass loss history of this class of stars. In this paper, we analyze the thermodynamical history to explore the neutrino observables of PPISNe. We compute the neutrino light curves and spectra during pulsation. We study the detailed neutrino emission profiles of these stars. Then, we estimate the expected neutrino detection count for different terrestrial neutrino detectors including, e.g., KamLAND and Super-Kamiokande. Finally, we compare the neutrino pattern of PPISN with other types of supernovae based on a canonical 10 kt detector. The predicted neutrino signals can provide the early warning for the telescopes to trace for the early time optical signals. Implications of neutrino physics on the expected detection are discussed.
