Primordial helium abundance determination using sulphur as metallicity tracer

27 Apr 2018 Fernández Vital Terlevich Elena Díaz Angeles I. Terlevich Roberto Rosales-Ortega F. F.

The primordial helium abundance $Y_P$ is calculated using sulphur as metallicity tracer in the classical methodology (with $Y_P$ as an extrapolation of $Y$ to zero metals). The calculated value, $Y_{P,\,S}=0.244\pm0.006$, is in good agreement with the estimate from the Planck experiment, as well as, determinations in the literature using oxygen as the metallicity tracer...
