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.

期刊介绍： Astrophysics (Ap) is a peer-reviewed scientific journal which publishes research in theoretical and observational astrophysics. Founded by V.A.Ambartsumian in 1965 Astrophysics is one of the international astronomy journals. The journal covers space astrophysics, stellar and galactic evolution, solar physics, stellar and planetary atmospheres, interstellar matter. Additional subjects include chemical composition and internal structure of stars, quasars and pulsars, developments in modern cosmology and radiative transfer.
