Abstract

We consider the role of the disk wind in the formation of hydrogen emission spectra of young intermediate-mass Herbig Ae stars. The assumed parameters for the kinematic characteristics of the wind region are typical of the theory of magnetocentrifugal disk winds. Our computations of the excitation and ionization states for atoms in the emitting region are based on the Sobolev approximation for a medium with a large velocity gradient. The calculations show that hydrogen-line emission profiles can have a complex structure that depends on the disk-wind parameters, as well as on the system’s orientation relative to the line of sight. The model proposed is able to explain most types of Hα profiles observed for Herbig Ae stars.
