KBO在南极的轨道成簇是由于太阳环场产生的时空拖曳吗？
Can Orbital Clustering of KBOs in the Ecliptic be due to the Solar Toroidal Field Generated Spacetime Dragging?
摘要：
柯伊伯带天体（KBO）的轨道上有一群外行星，它们的近日点距离大于海王星，半长轴距离太阳大于150天文单位。这意味着一个迄今为止未知的动力学机制，以对抗太阳系巨行星造成的轨道要素随机化。利用环向场引起的坐标系拖曳，在不假设海王星外天体（TNOs）引起的动力学效应的情况下，我们推导了柯伊伯带区域的观测范围、柯伊伯带中Sedna类天体的半长轴以及黄道中KBO的轨道成簇。我们还计算了内行星的轨道岁差率，并在观测精度范围内显示了它们与最近行星星历的对应关系。
英文摘要：
The Kuiper belt objects (KBOs) exhibit an orbital clustering of the outer planets lying at perihelion distances larger than Neptune and semimajor axes greater than 150 AU from the Sun. This implies a hitherto unknown dynamical mechanism to counter randomizing of the orbital elements caused by the giant solar system planets. Using the toroidal field induced frame-dragging we deduce here the observed range of the Kuiper belt region, the semi-major axis of Sedna like objects in the Kuiper belt, as well as the orbital clustering of the KBOs in the ecliptic, without assuming dynamical effects induced by trans-Neptunian-objects (TNOs). We also calculate the orbital precession rates for the inner planets and show their correspondence, within the range of observational accuracy, with recent planetary ephemerides.
