摘要
摘要 为了提高轨道运动和前冲预测的准确性,引入了考虑广义相对论效应的 vis-viva 公式的修改。更新后的方程在牛顿条件下简化为传统的 vis-viva 方程,是比传统方程更精确的天体动力学工具。初步模拟结果表明,修改后的 vis-viva 公式具有应用于更复杂 n 体系统的潜力。这种方法假定了球面对称性;不过,在未来的研究中可以消除这一限制。这项研究是连接经典力学和相对论力学的关键一步,因此对天体动力学领域做出了重要贡献。
General relativistic approach to the vis-viva equation on Schwarzschild metric
Abstract
A modification to the vis-viva equation that accounts for general relativistic effects is introduced to enhance the accuracy of predictions of orbital motion and precession. The updated equation reduces to the traditional vis-viva equation under Newtonian conditions and is a more accurate tool for astrodynamics than the traditional equation. Preliminary simulation results demonstrate the application potential of the modified vis-viva equation for more complex n-body systems. Spherical symmetry is assumed in this approach; however, this limitation could be removed in future research. This study is a pivotal step toward bridging classical and relativistic mechanics and thus makes an important contribution to the field of celestial dynamics.
