Abstract

Using the accretion shock wave model (Lamzin 1998), we calculate the relative intensities of the strongest intercombination lines in the range 1200-2000 Angstroms. We make a qualitative comparison of theoretical spectra with IUE low-resolution (~=6 Angstroms) spectra of T Tauri stars. We predict that several intercombination lines can be identified in spectroscopic observations of young stars with the Hubble Space Telescope and used for a quantitative comparison with the calculations.
