摘要：
Using non-LTE modeling for different components of the curcumstellar environment in Herbig AeBe stars, we reproduced hydrogen emission lines, such as Ha and H beta, and determined geometrical and physical parameters of the line emitting regions. Two Herbig stars (MWC 480 and IL Cep) have been considered. The modeling shows that the disk wind or X-wind are the main contributors to the radiation of the lines of the Balmer series compared to the magnetospheric accreting region.
