Resumen:
We present spectroscopic observations of 8 He-strong stars obtained at CASLEO and determine their fundamental parameters (Teff, log g, Mv and Mbol) using the BCD system as well as model fitting. We compare our values with others given in literature and discuss on the accuracy of these estimates. We also compute theoretical spectra with different He/H ratios in order to study the influence of this ratio on the Balmer discontinuity and the intensity of He and H lines.
