摘要

2021-2022 年在 FAI 对 7 颗 WC 和 WO 星进行了光度和光谱观测。在观测的基础上，我们获得了BVRc滤光片中天体亮度的估计值和发射线中辐射的绝对通量。在 WR 121 中探测到了 0m.1 - 0m.15 范围内的亮度变化。在几个天体的光谱中探测到了发射线通量的变化：WR 4、WR 5 和 WR 121。

Фотометрические и спектральные исследования группы галактических звезд Вольфа-Райе. Ii. WC и WO последовательности

Photometric and spectral observations of 7 WC and WO stars were carried out at the FAI in 2021-2022. On the base of observations we obtained estimates of the brightness of objects in the BVRc filters and absolute fluxes of radiation in the emission lines. Changes in brightness within 0m.1 - 0m.15 were detected in WR 121. Changes in the emission-line fluxes were detected in the spectra of several objects: WR 4, WR 5 and WR 121.
