摘要:

我们提出了一个数据库,以及确定的系外行星的轨道参数。这个数据库包括光谱轨道要素测量427行星绕363颗恒星的径向速度和过境测量报告中的文献。我们还编制了基本的过境参数,恒星参数,以及用于行星发现的方法。这个系外行星轨道数据库包括同行评审文章中报告的所有具有可靠,测量良好的轨道参数的行星。该数据库可以通过Exoplanets Data Explorer Table在 http://exoplanets.org上以可搜索、可过滤和可排序的形式提供,数据可以通过Exoplanets Data Explorer Plotter绘制和探索。我们使用的数据资源管理器生成出版准备图给出三个例子的签名的系外行星迁移和动力学演化:我们说明的字符的质量和周期的系外行星轨道,径向速度和过境调查之间的选择不同的偏差,和多行星系统显示出明显的半长轴分布从单点系统。

英文摘要:

We present a database of well determined orbital parameters of exoplanets. This database comprises spectroscopic orbital elements measured for 427 planets orbiting 363 stars from radial velocity and transit measurements as reported in the literature. We have also compiled fundamental transit parameters, stellar parameters, and the method used for the planets discovery. This Exoplanet Orbit Database includes all planets with robust, well measured orbital parameters reported in peer-reviewed articles. The database is available in a searchable, filterable, and sortable form on the Web at http://exoplanets.org through the Exoplanets Data Explorer Table, and the data can be plotted and explored through the Exoplanets Data Explorer Plotter. We use the Data Explorer to generate publication-ready plots giving three examples of the signatures of exoplanet migration and dynamical evolution: We illustrate the character of the apparent correlation between mass and period in exoplanet orbits, the selection different biases between radial velocity and transit surveys, and that the multiplanet systems show a distinct semi-major axis distribution from apparently singleton systems.
