Query: The underlying stellar absorption contribution to the primordial helium
  abundance determination   We carried out an exploratory analysis of the contribution of the underlying
stellar absorption to the total uncertainty of the abundance of primordial
helium using simple stellar populations models and observational data from the
Sloan Digital Sky Survey. Results indicate that our analysis yields a lower
limit to the error on the helium abundance determination if the stellar
absorption is neglected.
