摘要: We report on resonance-line profiles predicted by radiation-driven disk-wind models that extend radially 1 order of magnitude farther out than our previous models. Our main result is the inclusion a disk wind at larger radii changes qualitatively and quantitatively line new predict absorption significantly stronger those old Some exhibit double-humped structure near center now replaced more plausible single, blueshifted minimum. emphasize improvements in shape as well strength were achieved without changing gross properties wind. In particular, do not higher mass-loss rate did. The are due to fact ratio between rotational velocity poloidal decreases downstream. reproduce nova-like variable IX Vel promise observations other cataclysmic variables. This success model provides an important link outflows OB stars active galactic nuclei.
