论文摘要
自2018年9月以来，Lamost开始了中分辨率（r $ \ sim 7500 $）光谱调查（MRS）。我们提出了银河星云的光谱调查，包括\ hii \区域，HH物体，超新星残留物，行星星云和MRS MRS（Lamost MRS MRS-N）的特殊恒星。 Lamost Mrs-N覆盖北银河平面的约1700平方英尺，范围内$ 40^\ circ <l <215^\ circ $和$ -5^\ circ <b <5^\ circ $。在这项为期5年的调查中，我们计划观察约50万个星云光谱。根据调试观察，星云光谱可以提供精确的径向速度，不确定性小于1 km s $^{ - 1} $。这些高精度光谱数据对于我们对恒星形成和进化的理解具有重要意义。
Since Sep. 2018, LAMOST started the medium-resolution (R $\sim 7500$) spectral survey (MRS). We proposed the spectral survey of Galactic nebulae, including \hii\ regions, HH objects, supernova remnants, planetary nebulae and the special stars with MRS (LAMOST MRS-N). LAMOST MRS-N covers about 1700 square degrees of the northern Galactic plane within $40^\circ < l < 215^\circ$ and $-5^\circ < b < 5^\circ$. In this 5-year survey, we plan to observe about 500 thousand nebulae spectra. According to the commissioning observations, the nebulae spectra can provide precise radial velocity with uncertainty less than 1 km s$^{-1}$. These high-precision spectral data are of great significance to our understanding of star formation and evolution.
