中文总结 AI 辅助
该研究提出了一种含复杂度因子的边界条件,无需额外约束即可生成合理的中子星模型,发现消失的复杂度不适用于强引力致密天体边界。
中文摘要 AI 辅助
在球对称各向异性流体的边界处,生成了一种包含复杂度因子的新条件,该复杂度因子是黎曼张量正交分裂产生的结构标量。此条件无需对几何或物质变量施加其他额外约束即可生成模型,所生成模型具有物理合理性,且表明在表面处评估的复杂度标量值存在非零的正最小约束,这说明消失的复杂度是一种全局约束,不适用于边界,尤其不适用于强引力 regime 中的致密天体。
英文摘要
A new condition involving the complexity factor, a structure scalar arising from the orthogonal splitting of the Riemann tensor, is generated at the boundary of a spherically symmetric anisotropic fluid. This condition leads to the generation of a model, without invoking any further constraints on geometry or matter variables. The model generated is physically reasonable and suggests that there is a non-zero, positive minimum constraint on the complexity scalar value evaluated at the surface. This suggests that vanishing complexity is a globalized constraint which does not apply at the boundary, specifically for compact objects in the strong-gravity regime.
