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

Abstract

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.
