论文摘要
Algol C的光谱分类是Algol三重系统中的第三颗星，长期以来一直存在一些不确定性。有充分的理由怀疑它应该是金属线A型恒星，尤其是一项研究表明，这是这样的，但是进一步的研究对该评估产生了怀疑。在没有最亮恒星的光的情况下，我们利用了在原发性日食中和从原发性日食中采取的光谱中的简单光谱减法方法来揭示Algol C的光。我们所得的光谱与F1 V光谱标准相匹配，并没有显示金属线光谱异常的证据。我们注意到，此分类与该来源的最新丰度确定相匹配。
The spectral classification of Algol C, the third star in the Algol triple system, has long been a matter of some uncertainty. There is good reason to suspect that it should be a metallic-line A-type star, and one study in particular showed that this was so, but further studies have cast doubt on that assessment. We utilized a simple spectral subtraction method between spectra taken in and out of primary eclipse to reveal the light of Algol C in the absence of the light from the brightest star. Our resultant spectrum is well-matched to an F1 V spectroscopic standard and shows no evidence of metallic-line spectral anomalies. We note that this classification matches recent abundance determinations for this source.
