The Self Absorption Curve Method for the Analysis of Emission Lines of Complex Ions as a Diagnostic tellar envelope. Information can be obtained notably about the excitation conditions, the column density and the dimensions of the line emitting region, without making detailed model dependent complex radiative transfer computations. This method is particularly useful in the study of B[e] star envelopes.作者: Alpha-Cells 時(shí)間: 2025-3-23 02:02

Rapid Spectral Variability and Spatial and Kinematical Structure of Circumstellar Envelopes of Some tellar envelopes around peculiar Ae/Be stars. The method involved is based on a search for rapid line-profile variability of lines originating in different circumstellar regions. Analysis of these variations opens the way for reconstructing the density and velocity distributions throughout the envelope.作者: 紅腫 時(shí)間: 2025-3-23 10:40

High-Resolution Spectroscopy of HD 45677We present high-resolution spectra of the peculiar B[e] star HD 45677 (FS CMa) obtained at 3 observing nights. In our paper we focus on the variability of Balmer and neutral helium lines.作者: Keshan-disease 時(shí)間: 2025-3-24 12:57
The Galactic B[e] Supergiant Candidate HD 87643HD 87643 has long been known as a peculiar B-type emission line star. Its spectrum is dominated by emission lines from FeII and the Balmer series. Of particular note is the P Cygni shape of the hydrogen and helium lines. Except for the blue-shifted absorption components and interstellar absorption lines, no absorption lines have been found.作者: 泄露 時(shí)間: 2025-3-24 15:23 作者: indigenous 時(shí)間: 2025-3-24 20:36 作者: 推延 時(shí)間: 2025-3-25 02:40
