The low energy fusion cross sections of charged-particle nuclear reactions(and the respective reaction rates) in stellar plasmas are enhanced due toplasma screening effects. We study the impact of those effects on predictivestellar evolution simulations for detached double-lined eclipsing binaries. Wefollow the evolution of binary systems (pre-main sequence or main sequencestars) with precisely determined radii and masses from 1.1Mo to 23Mo (fromtheir birth until their present state). The results indicate that all thediscrepancies between the screened and unscreened models (in terms ofluminosity, stellar radius, and effective temperature) are within theobservational uncertainties. Moreover, no nucleosynthetic or compositionalvariation was found due to screening corrections. Therefore all thermonuclearscreening effects on the charged-particle nuclear reactions that occur in thebinary stars considered in this work (from their birth until their presentstate) can be totally disregarded. In other words, all relevantcharged-particle nuclear reactions can be safely assumed to take place in avacuum, thus simplifying and accelerating the simulation processes.Comment: 5 RevTex pages,no figures.
