SONG in New Mexico is a robotic telescope combined with an ultra-precise spectrograph that will be an addition to the Stellar Observations Network Group (SONG). This international collaboration will obtain near-continuous observations of bright, oscillating stars in order to study their structure. Understanding stars is a fundamental goal of astrophysics as stars are the most basic building blocks of galaxies and the universe. This will be the only U.S. participating facility in the global SONG project. It will provide the key link to allow 24-hour coverage that is needed to accomplish the scientific goals. The observations will lead to an improved understanding of a wide variety of stars, including target stars that host Earth-like planets. This new facility overlaps significantly with the interests of the students and faculty in astronomy at New Mexico State University, providing long-term educational and research benefits and commitment.Oscillating stars have turbulent motions within them that generate sound waves that cause the majority of them to wobble and ring like bells. The measurement and analysis of these acoustic oscillations is the primary means to study the interior of a star. This project will acquire and assemble a telescope and spectrograph instrument that will close a gap in the world-wide SONG network dedicated to monitoring oscillating stars 24 hours per day. The state-of-the-art spectrograph comes from a well-tested design and has already demonstrated radial-velocity precision of about 1 meter-per-second. The goals this facility enables are to perform asteroseismology of stars to obtain the most detailed information possible, and to search for and characterize Earth-like planets around Sun-like stars. It complements past, current, and future space missions with similar science goals.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

新墨西哥州的Song是一种机器人望远镜，结合了超专有光谱仪，它将成为Stellar观测网络组（Song）的补充。这项国际合作将对明亮，振荡的恒星几乎连续观察，以研究其结构。 理解恒星是天体物理学的基本目标，因为星星是星系和宇宙的最基本的基础。这将是全球歌曲项目中唯一的美国参与设施。它将提供关键链接，以允许实现科学目标所需的24小时覆盖范围。这些观察结果将导致人们对各种恒星的了解，包括托有类似地球行星的目标恒星。这种新设施与新墨西哥州立大学的天文学的学生和教职员工的利益重叠，提供了长期的教育和研究福利和承诺。苏联恒星内部具有动荡的动作，产生了声音，这会导致大多数人像铃铛一样摇摆和铃响。这些声学振荡的测量和分析是研究恒星内部的主要手段。该项目将获取并组装望远镜和光谱仪仪器，该工具将弥合全球歌曲网络中的差距，该网络致力于每天24小时监视振荡星。最新的光谱仪来自经过良好测试的设计，并且已经显示出每秒约1米的径向速度精度。该设施的目标是执行恒星的星形学，以获取可能的最详细信息，并搜索和表征周围类似太阳恒星的地球状行星。它以相似的科学目标补充了过去，当前和未来的空间任务。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子和更广泛影响的评论标准来评估值得支持的。
