抽象的。LAMOST-MRS-B是LAMOST中分辨率($Rsim 7500 $)光谱巡天的子巡天之一。它的目的是研究双星和奇异星的统计特性(如双星分数、轨道周期分布、质量比分布)。我们打算观测大约30,000颗恒星(95%的晚型和早型恒星分别为10 leq G-1。本文提供的数据集可在科学数据库中获得。
Abstract. LAMOST-MRS-B is one of the sub-surveys of LAMOST medium-resolution ($Rsim7500$) spectroscopic survey. It aims at studying the statistical properties (e.g. binary fraction, orbital period distribution, mass ratio distribution) of binary stars and exotic stars. We intend to observe about 30,000 stars ($10leq G -1 for 95% of late- and early-type stars, respectively. The datasets presented in this paper is available in Science Data Bank.
