核塌缩超新星的广义相对论爆炸模型

General Relativistic Explosion Models of Core-Collapse Supernovae

Bernhard Mueller, Andreas Marek, Hans-Thomas Janka, Harald Dimmelmeier

摘要:

我们目前的结果,从第一代多维广义相对论中微子流体动力学模拟核心坍缩超新星。与使用纯牛顿近似或“有效引力势”方法计算的模型进行比较,发现加热条件和引力波谱存在明显的定量差异。我们的研究结果强调了广义相对论在超新星问题中的重要作用(这似乎与其他重要因素,如维数和状态方程),无论是我们的爆炸动力学的理解,以及可观察到的签名的预测。

英文摘要:

We present results from the first generation of multi-dimensional general relativistic neutrino hydrodynamics simulations of core-collapse supernovae. A comparison with models computed using either the purely Newtonian approximation or the "effective gravitational potential" approach reveals appreciable quantitative differences in the heating conditions and the gravitational wave spectra. Our results underscore the important role of general relativity in the supernova problem (which appears to be on par with other important factors such as the dimensionality and the equation of state) both for our understanding of the explosion dynamics as well as for predictions of observable signatures.
