Zusammenfassung:We present a spectroscopc study of the hot Algol-type system u Her (68 Her, B2 IV + B8 III). A new set of high-resolution échelle spectra has been obtained at Calar Alto Observatory. Spectral disentangling allowed isolation of the individual spectra of the components. A detailed spectroscopic analysis of the primary star indicates an abundance pattern resulting from CNO processing.
