Scientific paper

An indirect method for determining the helium content of G-K dwarfs and subdwarfs relies on the fact that the position of a main sequence star in the theoretical H-R diagram, derived from internal structure computations, depends only on the two fundamental parameters Y and Z (helium and heavy element abundances), and that the helium content of a star of known metallicity can be inferred from the empirical location of the star in the H-R diagram.
