摘要

2021-2022 年，费森科夫天体物理研究所对 WC 和 WO 序列中的 7 颗恒星进行了光度和光谱观测。这些观测数据是估算天体在 BVRc 滤光片中的亮度和发射线辐射绝对通量的基础。记录了 WR 121 在 0m.1-0m.15 范围内的亮度变化。在 WR 4、WR 5、WR 121 和 WR 128 等天体的光谱中探测到了发射线通量的变化。

Photometric and Spectral Studies of a Group of Wolf-Rayet Galactic Stars. II. WC and WO Sequences

Photometric and spectral observations of 7 stars in the WC and WO sequences were made at the Fesenkov Astrophysical Institute in 2021-2022. These observations served as the basis of estimates of the brightness of the objects in BVRc filters and the absolute fluxes of radiation in the emission lines. Changes in the brightness of WR 121 over the limits of 0^m.1-0^m.15 were recorded. Changes in the fluxes of emission lines were detected in the spectra of several of the objects, WR 4, WR 5, WR 121, and WR 128.

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.
