On the possible interaction between magnetic field and HII region in AB Aurellar wind in the line-forming region, we observe an emission component in the blue side of the absorption feature (Beals Type III profile). Furthermore, the combined effects of the oblique rotator geometry and the mass loss produced by the centrifugal force give rise to the changing Type II P Cyg p作者: 流出 時(shí)間: 2025-3-29 06:15 作者: Irascible 時(shí)間: 2025-3-29 09:21
