Description:
Properties of Very Low mass stars for different initial metallicity
[M/H] and Helium mass fraction: mass (in solar mass), age (in Gyrs)
effective temperature (in K), log of luminosity (in solar L), radius
(10^10cm), central temperature Tc (in K) and density RHOc (in
gr/cm-3). Abundances of light elements are normalised to their initial
abundance (see text).
