With the advent of modern neutrino and gravitational wave detectors, the promise of multi-messenger detections of the next galactic core-collapse supernova has become very real. Such detections will give insight into the core-collapse supernova mechanism, the structure of the progenitor star, and may resolve longstanding questions in fundamental physics. In order to properly interpret these detections, a thorough understanding of the landscape of possible core-collapse supernova events, and their multi-messenger signals, is needed. We present detailed predictions of neutrino and gravitational wave signals from 1D simulations of stellar core collapse, spanning the landscape of core-collapse progenitors from $9-120\,\mathrm{M}_{\odot}$. In order to achieve explosions in 1D, we use the STIR model, which includes the effects of turbulence and convection in 1D supernova simulations to mimic the 3D explosion mechanism. We study the gravitational wave emission from the 1D simulations using an astroseismology analysis of the proto-neutron star. We find that the neutrino and gravitational wave signals are strongly correlated with the structure of the progenitor star and remnant compact object. Using these correlations, future detections of the first few seconds of neutrino and gravitational wave emission from a galactic core-collapse supernova may be able to provide constraints on stellar evolution independent of pre-explosion imaging and the mass of the compact object remnant prior to fallback accretion.

用多信使信号约束下一颗邻近核心坍缩超新星的特性

随着现代中微子和引力波探测器的出现，多信使探测下一颗星系核坍缩超新星的前景变得非常真实。此类探测将深入了解核心坍缩超新星机制、祖星的结构，并可能解决基础物理学中长期存在的问题。为了正确解释这些探测，需要彻底了解可能的核心坍缩超新星事件的格局及其多信使信号。我们从恒星核心坍缩的一维模拟中给出了对中微子和引力波信号的详细预测，涵盖了 $9-120\,\mathrm{M}_{\odot}$ 的核心坍缩祖细胞的景观。为了实现一维爆炸，我们使用 STIR 模型，其中包括 1D 超新星模拟中湍流和对流的影响，以模拟 3D 爆炸机制。我们使用原中子星的天体地震学分析来研究来自一维模拟的引力波发射。我们发现中微子和引力波信号与前身星和残余致密物体的结构密切相关。使用这些相关性，未来对来自星系核坍缩超新星的前几秒中微子和引力波发射的探测可能能够提供对恒星演化的约束，而不受爆炸前成像和回落前致密物体残余物的质量的影响吸积。我们使用原中子星的天体地震学分析来研究来自一维模拟的引力波发射。我们发现中微子和引力波信号与前身星和残余致密物体的结构密切相关。使用这些相关性，未来对来自星系核坍缩超新星的前几秒中微子和引力波发射的探测可能能够提供对恒星演化的约束，而不受爆炸前成像和回落前致密物体残余物的质量的影响吸积。我们使用原中子星的天体地震学分析来研究来自一维模拟的引力波发射。我们发现中微子和引力波信号与前身星和残余致密物体的结构密切相关。使用这些相关性，未来对来自星系核坍缩超新星的前几秒中微子和引力波发射的探测可能能够提供对恒星演化的约束，而不受爆炸前成像和回落前致密物体残余物的质量的影响吸积。
