论文摘要
近年来，人们对重力几个身体问题及其在天体物理场景中的应用正在越来越多。引起这种新兴趣的主要原因之一，有大量新发现的系外行星和重力波的检测。在这里，我们提出了两个数值代码，以模拟三体和几个体系，称为海啸和冲绳。海啸代码是具有算法正则化，潮汐力和牛顿后校正的直接几个体制代码。 Okinami是稳定分层的世俗，双重平均代码。我们描述了代码中实施的主要方法，并回顾了我们对重力波天文学，行星科学和统计逃生理论的最新结果和应用。
In recent years, an increasing amount of attention is being paid to the gravitational few-body problem and its applications to astrophysical scenarios. Among the main reasons for this renewed interest there is large number of newly discovered exoplanets and the detection of gravitational waves. Here, we present two numerical codes to model three- and few-body systems, called TSUNAMI and OKINAMI. The TSUNAMI code is a direct few-body code with algorithmic regularization, tidal forces and post-Newtonian corrections. OKINAMI is a secular, double-averaged code for stable hierarchical triples. We describe the main methods implemented in our codes, and review our recent results and applications to gravitational-wave astronomy, planetary science and statistical escape theories.
