标题： Discovery of the first Super-Lithium rich Beat Cepheid: V371 Per

摘要： 四次高分辨率光谱首次获得的双模造父变星V371 Per，显示了异常强的Li I 6707.76 A线的存在。 我们对轻元素丰度的分析表明，这颗恒星没有经历演化的冲刷阶段。 远离银河系平面和低金属量表明，V371 Per可能属于银河系的厚盘（或晕），这与其低金属量[Fe/H]=-0.42以及相对于铁的α-和s-元素增强一致。 在其中一条光谱中观察到了谱线分裂，这可能是由于非径向脉动所致。 显示英文摘要

摘要： Four high-resolution spectra of the double-mode Cepheid V371 Per, obtained for the first time, showed the presence of the abnormally strong Li I 6707.76 A line. Our analysis of the light element abundances indicates that the star did not go through the evolutionary dredge-up stage. Large distance from the galactic plane and the low metallicity suggest that V371 Per may belong to the thick disc (or to the halo) of the Galaxy, which is consistent with its low metallicity [Fe/H]=-0.42 and the enhancement of the alpha- and s-elements relative to iron. Line splitting is observed in one of the spectra, which can be due to the non-radial pulsations.
