Tracing CNO Exposed Layers in the Hot Algol-Type Binary System 68 Her

  • A. Dervişoğlu (a1), K. Pavlovski (a2), V. Kolbas (a2) and J. Southworth (a3)


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.
