| 内容記述 | Emission line fluxes were used to establish the emission measure distribution for T Tau and RU Lupi. Intersystem lines are used to constrain the electron density in the emitting regions. These are compared with the results of Alfven wave driven wind models. Observed emission line widths and absorption components formed in the stellar winds are also compared with the theoretical predictions. It is concluded that the transition region lines are not formed in the wind and that the large widths of these emission lines are caused by nonthermal turbulent motions. However, the intersystem lines formed at Te less than or = 10,000 K indicate the presence of a lower density region, identified with the wind. Alfven-wave driven winds, with T max = 10,000 K long damping lengths, and high initial wave amplitudes may be able to account for the observed characteristics. |
