Scientific paper

The evolutionary models of partially mixed stars were constructed by considering the degree of mixing and of nonthermal pressure support as parameters. The distribution of blue stragglers in the old open cluster NGC 7789 is compared with unmixed and mixed models; theoretical time-constant loci for mixed models show that the distribution of blue stragglers can be explained in this manner. The mass distribution is concentrated in the 1.7-2.2 solar mass range, so that no straggler in this cluster requires a finite nonthermal pressure. It is concluded that extensive internal mixing is a valid hypothesis for the existence of blue stragglers.
