论文摘要
我们提出开源Python代码二进制式摩尔刀，该代码求解光谱二进制系统的轨道元素。给定径向速度测量的时间序列，确定了六个轨道参数：长期的平均值，或全身性，径向速度，速度振幅，periastron的论点，偏心率，Periastron的时期和轨道时期，以及节期$ \ \ \ \ {up \ f. {up} $ {up {还返回给用户的是半高轴的预计长度，$ a_ {1} \ sin（i）$，质量函数$ f（m）$。光谱轨道和质量的确定是天体物理学的另一个重要领域的一个例子，曾经是专业天文学家的领域，业余爱好者现在可以做出重大贡献。该代码可从GitHub获得，以支持该工作，应一般使用业余和专业的天文学界。
We present the open source Python code BinaryStarSolver that solves for the orbital elements of a spectroscopic binary system. Given a time-series of radial velocity measurements, six orbital parameters are determined: the long-term mean, or systemic, radial velocity, the velocity amplitude, the argument of periastron, the eccentricity, the epoch of periastron, and the orbital period referred to by $\{{γ, K, ω, e, T_0, P}\}$ respectively. Also returned to the user is the projected length of the semi-major axis, $a_{1}\sin(i)$, and the mass function, $f(M)$. The determination of spectroscopic orbits and masses is an example of another important area of astrophysics, once the domain of professional astronomers, to which amateurs can now make significant contributions. This code, available from GitHub, is provided in support of that work, and should be of general use to the amateur and professional astronomical community.
