Resumen:
We study the atmospheric structure of hot stars by means of the analysis of ultraviolet line profiles of Si IV. Our goal is to obtain velocity and temperature laws of the wind as well as ionization structures for atmospheres in NLTE and with radiative equilibrium departures. We present a possible explanation on the appearance of narrow absorption components in Si IV line profiles.
