$χ$ Lupi A光谱中的谱线识别
Line identifications in the spectrum of $χ$ Lupi A
摘要：
我们提出了新的丰度测定的尖锐线HgMn星XLupi A档案FEROS光谱。选择具有精确原子数据的未混合谱线进行合成，以获得χ Lupi A的新丰度。这些光谱显示了伴星XLupi B的蓝移谱线的存在。对狼座χ B光谱的合成证实了这颗恒星温度较低，可能是一颗早期的A星，丰度正常。
英文摘要：
We present new abundance determinations for the sharp-lined HgMn star χ Lupi A from archival FEROS spectra. Selected unblended lines with accurate atomic data have been synthesized to derive new abundances for χ Lupi A. These spectra show evidence of the presence of blue-shifted lines of the companion χ Lupi B. The synthesis of the spectrum of χ Lupi B confirms that this star is cooler, probably an early A star with normal abundances.
