Observations of Boron, an easily destroyed element, will be used to probe processes which circulate or remove and destroy material in cool stars. These include mass loss, diffusion, meridional circulation, convective overshoot, and turbulence and rotationially-driven mixing. 1. The destruction of light elements in the sun is not understood but is a key to understanding internal mixing in cool stars. Alpha Centauri A and B will be measured to study mixing in stars respectively slightly more and less massive than the sun. Beta Hyi will be studied as an example of a 1.0 solar mass, partially evolved star. 2. The rates of mixing processes, especialy those which are expected to operate only on long timescales, will be studied by observing two stars in the intermediate age cluster NGC 752. One star will be from inside the "Lithium Gap" region in the F stars, and one star from outside the gap. 3. Two red giants and subgiants will be observed to help measure the amount of mass lost on the giant branch. . . . . . . . . . . . . . . . . . . . . . . NOTE: THIS PROPOSAL ONLY USES SIDE 2 OF THE GHRS. We are aware of the GHRS condition (as the P.I. is GHRS Instrument Scientist.)
