FORBIDDEN-LINE FORMATION IN HYDROMAGNETIC DISK WINDS .2. LINE-PROFILES

In Paper I of this work, we constructed a model for oblique shocks in recollimating, non-self-similar hydromagnetic disk winds. We showed that such a model provides a natural explanation for the basic features of the emitting region. In this second part Of OUT investigation, we calculate the expected line ratios, line intensities and line profiles of the forbidden lines [O I] lambda6300, [S II] lambdalambda6716, 6731, and [N II] lambda6548 produced in this way. Good fits to the profiles are found for models with rather modest magnetosonic Mach numbers, n1 less-than-or-equal-to 4. We find double-peaked profiles whose lower velocity component is nearly at zero velocity. The profiles have extended blue wings which arise from the variation of terminal wind speed with disk radius. The flux in the lines is proportional to the mass accretion rate M(a) through the disk. This result follows from the relation, M(w) congruent-to 10(-1) M(a), which is a consequence of the efficient angular momentum removal from the disk by the wind.
