SYNTHETIC ABSORPTION-LINE STRENGTHS IN STAR-FORMING REGIONS, AND THE EFFECTS ON THE HELIUM ABUNDANCE DETERMINATION

• Spectral evolutionary calculations have been employed in order to follow the behaviour of absorption lines in single-burst star forming regions. The model calculations are based on theoretical evolutionary tracks and model atmosphere stellar spectra at 5
