In this thesis the author presents an analytical model for the magnetic flux surfaces for rapidly rotating magnetized young stellar objects which is based on ideal, stationary, axisymmetric magnetohydrodynamics. The resulting cold wind solutions reproduce observed wind velocities of a few hundred km s-1 and the outer jet radius for a collimated jet of several thousand stellar radii. The calculated velocity, density and temperature distributions are used as input for the 3D radiative transfer. Atomic line and continuum absorption is included as well as the stellar continuum. Depending on the treatment of the z-axis and the transparency of the disk one obtains single-, double- or triple-peaked forbidden emission line profiles. Then the blueshifted jet shows a high-velocity (HVC), a low-velocity (LVC) and/or a near-rest-velocity (NRVC) component. The HVC is in agreement with observations, whereas the LVC is too far off from the star. The line luminosity is at the high end of measured values.
