The vibrational stability towards radial oscillations of homogeneous main sequence stars initially composed of 80 percent of hydrogen and 20 percent of helium in mass and no metals is studied. During the pre-main sequence phase, enough carbon is accumulated to trigger the CN-cycle. The critical mass for vibrational stability is found to be 123 solar masses.
