摘要

2021-2022年期间，在AFIF对WN序列的11颗狼-雷叶星进行了光度和光谱观测。在这些观测的基础上，获得了BVRc滤光片中天体亮度的估计值和该星群中发射线辐射的绝对通量。记录了 WR I 星中 WR 120、WR 151 和 WR 152 在 0m.1-0m.15 范围内的亮度变化。在几个天体的光谱中检测到了发射通量的变化：WR 120、WR 128 和 WR 145。

Photometric and Spectral Studies of the Group of Galactic Wolf-Rayet Stars. I. WN Sequence

Photometric and spectral observations of 11 Wolf-Rayet stars of the WN sequence were made at the AFIF during 2021-2022. Estimates of the brightness of objects in BVRc filters and the absolute fluxes of radiation in emission lines in this group are obtained on the basis of these observations. Changes in the brightness over a range of 0^m.1-0^m.15 are recorded for the stars WR 120, WR 151, and WR 152 in the WR I stars. Changes in the emission fluxes are detected in the spectra of several objects: WR 120, WR 128, and WR 145.

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.
