- Аннотация: A steady-state structure and spectrum of the accretion zone at the surface of T Tauri stars are numerically simulated. This modeling uses well-developed methods of the theory of stellar atmospheres with inclusion of the effects of the gas motion (advection and the doppler shift of the lines). The spectrum Iν (μ) and cooling rate of shocked gas are calculated. It is found that at the pre-shock densities N0>10^13 cm–3 helium and hydrogen lines show a red-shifted absorption, significantly broadened by the Stark effect.
