RAVE database

RAVE (RAdial Velocity Experiment) is a multi-fiber spectroscopic astronomical survey of stars in the Milky Way using the 1.2-m UK Schmidt Telescope of the Anglo-Australian Observatory (AAO). The RAVE collaboration consists of researchers from over 20 institutions around the world and is coordinated by the Leibniz-Institut für Astrophysik Potsdam. As a southern hemisphere survey covering 20,000 square degrees of the sky, RAVE's primary aim is to derive the radial velocity of stars from the observed spectra. Additional information is also derived such as effective temperature, surface gravity, metallicity, photometric parallax and elemental abundance data for the stars. The survey represents a giant leap forward in our understanding of our own Milky Way galaxy; with RAVE's vast stellar kinematic database the structure, formation and evolution of our Galaxy can be studied.

RAVE（RAdial Velocity Experiment，径向速度实验）是一项利用澳大利亚英澳天文台1.2米UK施密特望远镜对银河系恒星进行的多纤维光谱天文观测项目。RAVE合作团队由全球20多个机构的科研人员组成，并由波茨坦的莱布尼茨天体物理研究所协调。作为一项覆盖20,000平方度天区的南半球观测项目，RAVE的主要目标是通过对观测光谱的分析，推导出恒星的径向速度。此外，该观测还提供了诸如有效温度、表面重力、金属丰度、视差测量和元素丰度等额外信息。该调查标志着我们对自身银河系理解的一次巨大飞跃；凭借RAVE庞大的恒星动力学数据库，我们可以研究银河系的构造、形成与演化。
