AI总结：
本研究通过数值模拟分析小行星质量原初黑洞对太阳系行星轨道的扰动，发现其效应小于当前测量误差，需提高测距精度一个数量级或提取低噪声信号方可探测。
摘要：
如果小行星质量的原初黑洞（PBHs）构成全部暗物质，它们可能通过其在太阳系中的引力影响而被探测到。在这项工作中，我们研究了原初黑洞对行星轨道引起的扰动。我们进行了嵌入在原初黑洞晕中的太阳系的详细数值模拟。我们发现，原初黑洞的引力效应由最近的一次相遇主导。利用地球-火星距离作为观测探针，我们表明这些扰动小于当前的测量不确定性，因此原初黑洞不受太阳系历表的直接约束。我们估计，需要将测距精度提高一个数量级，或者提取远低于噪声水平的信号，才能在可预见的未来探测到原初黑洞在太阳系中的引力影响。
英文摘要：
If primordial black holes (PBHs) of asteroidal mass make up the entire dark matter, they could be detectable through their gravitational influence in the solar system. In this work, we study the perturbations that PBHs induce on the orbits of planets. Detailed numerical simulations of the solar system, embedded in a halo of PBHs, are performed. We find that the gravitational effect of the PBHs is dominated by the closest encounter. Using the Earth-Mars distance as an observational probe, we show that the perturbations are smaller than the current measurement uncertainties and thus PBHs are not directly constrained by solar system ephemerides. We estimate that an improvement in the ranging accuracy by an order of magnitude or the extraction of signals well below the noise level is required to detect the gravitational influence of PBHs in the solar system in the foreseeable future.
