摘要

HD 66051 (V414 Pup)是一颗食相和光谱双星，拥有两颗化学性质奇特的恒星:一颗非常奇特的B星是主恒星，一颗Am星是副恒星。它还显示了由化学斑点引起的月食外的变化。通过一组高分辨率的偏振光谱观测，在原星上发现了一个弱磁场。对HD 66051新的高分辨率紫外光谱的研究使我们能够更可靠地确定两种成分的化学特性类型。

The enigmatic highly peculiar binary system HD 66051

HD 66051 (V414 Pup) is an eclipsing and spectroscopic double-lined binary, hosting two chemically peculiar stars: a highly peculiar B star as primary and an Am star as secondary. It also shows out-of-eclipse variability that is due to chemical spots. Using a set of high-resolution spectropolarimetric observations, a weak magnetic field on the primary was found. The investigation of the new high-resolution UVES spectrum of HD 66051 allowed us to decide on the chemical peculiarity type of both components with more reliability.
