  A grid of stellar evolution models for Procyon A has been calculated. These
models include the best physics available to us (including the latest opacities
and equation of state) and are based on the revised astrometric mass of Girard
et al (1996). Models were calculated with helium diffusion and with the
combined effects of helium and heavy element diffusion. Oscillation frequencies
for l=0,1,2 and 3 p-modes and the characteristic period spacing for the g-modes
were calculated for these models. We find that g-modes are sensitive to model
parameters which effect the structure of the core, such as convective core
overshoot, the heavy element abundance and the evolutionary state (main
sequence or shell hydrogen burning) of Procyon A. The p-modes are relatively
insensitive to the details of the physics used to model Procyon A, and only
depend on the evolutionary state of Procyon A. Hence, observations of p-mode
frequencies on Procyon A will serve as a robust test of stellar evolution
models.
