我们提出了一个新的辛算法，具有理想的性能，能够集成密切近日点通道与太阳。我们将该算法与研究微行星动力学和行星形成的快速高效算法（称为SyMBA）结合起来。由此产生的代码可以在模拟过程中将所有对象之间的紧密接触辛式地集成，从而消除了SyMBA（和相关方案）的主要限制。我们相信，这个算法将是一个宝贵的工具，研究行星形成的激烈阶段。
We present a new symplectic algorithm that has the desirable property of being able to integrate close perihelion passages with the Sun. We have combined this algorithm with our fast and efficient algorithm for studying planetesimal dynamics and planet formation, known as SyMBA. The resulting code can symplectically integrate close encounters between all objects during a simulation, thus removing the main limitation of SyMBA (and related schemes). We believe that this algorithm will be a valuable tool for the study of the violent stages of planet formation.
