论文摘要

提出了第9行,以解释某些跨神经物体的轨道聚类。最近,提出了次忠实的航天器的使用,以间接探测行星9的重力影响。 Here we study the effects of the drag and electromagnetic forces exerted on a sub-relativistic spacecraft by the interstellar medium (ISM) and compare these forces with the gravitational force induced by Planet 9. We find that the resulting noise due to density and magnetic fluctuations would dominate over Planet 9's gravitational signal at sub-relativistic speeds, $v\gtrsim 0.001~c$.然后,我们确定从ISM湍流中克服阻力和磁性噪声所需的参数空间,并能够检测9号行星的重力。最后,我们讨论了减轻阻力和电磁力的影响的实用策略。

Planet 9 was proposed as an explanation for the clustering of orbits for some trans-Neuptunian objects. Recently, the use of a sub-relativistic spacecraft was proposed to indirectly probe Planet 9's gravitational influence. Here we study the effects of the drag and electromagnetic forces exerted on a sub-relativistic spacecraft by the interstellar medium (ISM) and compare these forces with the gravitational force induced by Planet 9. We find that the resulting noise due to density and magnetic fluctuations would dominate over Planet 9's gravitational signal at sub-relativistic speeds, $v\gtrsim 0.001~c$. We then identify the parameter space required to overcome the drag and magnetic noise from the ISM turbulence and enable the detection of Planet 9's gravity. Finally, we discuss practical strategies to mitigate the effect of the drag and electromagnetic forces.
