摘要:

描述了盾牌座$(ubvy-β$变星\astrobj{7 Aql}和\astrobj{8 Aql}的光度观测和光谱观测。导出了这两颗星的Strömgren标准指数和物理参数。考虑到光谱学和光度学的结果,将F0 V和F2 III的光谱类型分别指定为\astrobj{7 Aql}和\astrobj{8 Aql}。还分析了微分$uvby$光曲线。进行了多色模式识别的尝试。

英文摘要:

Photometric $(ubvy-β$) and spectroscopic observations of the $δ$ Scuti variables \astrobj{7 Aql} and \astrobj{8 Aql} are described. The Strömgren standard indices and physical parameters of both stars are derived. Spectral types of F0V and F2III have been assigned to \astrobj{7 Aql} and \astrobj{8 Aql} respectively considering the results from both spectroscopy and photometry. Differential $uvby$ light curves were also analyzed. A attempt of multicolour mode identification is carried out.
