We have studied the interstellar lines and diffuse bands in the spectrum of the supergiant κ Cas using the CCD spectra obtained with the Echelle spectrograph of the 2 meter telescope at the peak Terskol observatory. A synthetic stellar spectrum was used to correctly reveal the interstellar features, computed for a model atmosphere with T_eff = 21 500 K, log g = 2.60, v sin i = 83 kms^-1, [M/H] = 0.0, ξ = 15 kms^-1 and with partial selection of main chemical element abundances. Eleven interstellar bands and 91 diffuse interstellar bands were identified. A further 14 absorption features were revealed, possibly also diffuse bands. The spectrophotometric diffuse band parameters and their accuracies were tabulated. We present maps of observed and synthetic spectral regions containing interstellar diffuse bands.

超巨κCas光谱中的星际线和扩散带

我们研究了星际线和扩散条带在超巨星的频谱κ CAS大全MSDS使用具有2米望远镜在峰值Terskol天文台的阶梯光栅光谱仪获得的CCD光谱。使用合成恒星光谱正确显示星际特征，这是针对模型大气计算得出的，其中T _eff = 21 500 K，log g = 2.60，v sin i = 83 kms ^{- 1}，[M / H] = 0.0，ξ = 15公里^{- 1}并部分选择主要化学元素的丰度。确定了11个星际带和91个弥散星际带。揭示了另外14个吸收特征，可能还有扩散带。将分光光度扩散带参数及其精度制成表格。我们提供了包含星际漫射带的观测和合成光谱区域的地图。
