Accurate stellar parameters are presented for the F- and G-type stars And, Cnc, Boo, 16 Cyg, and CrB, which are deemed to possess planetary companions from intense Doppler monitoring. Evolutionary tracks that employ detailed model atmospheres as upper boundary condition and allow for helium diffusion are computed for the individual stars to derive the stellar masses and ages. From a comparison of the spectroscopic parallaxes with the accurate distances available from the Hipparcos satellite well-defined constraints on the stellar surface gravities are obtained in good agreement with our spectroscopically deduced values.
