Abstract
Фотометрические и спектральные наблюдения 11-ти звезд Вольфа-Райе WN последовательности выполнялись в АФИФ в 2021-2022гг. На основе проведенных наблюдений получены оценки блеска объектов в фильтрах BVRc и абсолютные потоки излучения в эмиссионных линиях. Изменения блеска в пределах 0m.1 - 0m.15 зарегистрированы в звездах WR 1, WR 120, WR 151, WR 152. Изменения эмиссионных потоков обнаружены в спектрах нескольких объектов: WR 120, WR 128, WR 145.
Photometric and spectral observations of 11 W-R stars were carried out at the FAI in 2021-2022. The studied group included representatives of the WN, WC, and WO sequences. Based on the observations estimates of the brightness of objects in the B V Rc filters and absolute fluxes of radiation in the emission lines were obtained. Changes in brightness within 0m.1 - 0m.15 were detected in the stars WR 1, WR 120, WR 151, and WR 152. Changes in the emission fluxes were 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.
