Descripción
Preliminary results are presented of spectroscopic analysis of ten young
stars in OB associations using high resolution spectra and NLTE
calculations. From the known distances the stellar masses are derived.
The comparison with evolutionary tracks indicates a possible discrepancy
between the masses and enhanced helium abundances derived from the
tracks and from the analysis.
