符号回归从引力波近似中子星半径

作者 PulseAugur 编辑部 · [1 个来源] · 2026-09-15 04:00

研究人员开发了一种符号回归方法 pySR，仅使用引力波测量来近似中子星半径。该方法旨在通过实现引力波数据与电磁观测之间的比较来增强多信使天文学研究。该方法在 TOV 解上进行了训练，并针对各种状态方程进行了测试，显示出与真实值一致的同意，并实现了几百米的平均半径差异。当应用于 GW170817 事件时，该近似产生了与先前推断的半径分布相当的半径分布。 AI

影响这项研究可以通过实现中子星不同观测通道之间更直接的比较来改进天体物理分析。

使用符号回归的仅引力波测量来近似中子星半径

arXiv:2504.19962v3 Announce Type: cross Abstract: Gravitational waves emitted by binary neutron-star inspirals carry information on components' masses and tidal deformabilities, but not directly radii, which are measured by electromagnetic observations of neutron stars. To improv…
