MODELING ULTRAVIOLET WIND LINE VARIABILITY IN MASSIVE HOT STARS

摘要

We model the detailed time-evolution of discrete absorption components (DACs) observed in P Cygni profiles of the Si Ⅳ λ 1400 resonance doublet lines of the fast-rotating supergiant HD 64760 (BO.5 Ib). We adopt the common assumption that the DACs are caus
