Descripción
We present two independent methods for studying the global stellar
parameter space (mass M, age, chemical composition X0,
Z0) of HD 49933 with seismic data. Using a local minimization
and an MCMC algorithm, we obtain consistent results for the
determination of the stellar properties: M = 1.1-1.2 M&sun;
Age ~ 3.0 Gyr, Z0 ~ 0.008. A description of the error
ellipses can be defined using Singular Value Decomposition techniques,
and this is validated by comparing the errors with those from the MCMC
method.
