Metallicity of mono- and multiperiodic β Cephei stars.

DASZYNSKA-DASZKIEWICZ J. and NIEMCZURA E.

Abstract (from CDS):

Analyzing IUE ultraviolet spectra of β Cep pulsating stars we noticed that multiperiodic variables have a larger mean metal abundance in the photosphere, [m/H], than monoperiodic ones. We apply statistical tests to verify this dichotomy. We obtain that, with a large probability, the multiperiodic β Cep stars have greater values of [m/H]. This result is consistent with the linear non-adiabatic theory of pulsation of early B-type stars.
