These include mass loss, diffusion, meridional circulation, line_4: convective overshoot, and turbulence and rotationially-driven mixing. line_5: 1. The destruction of light elements in the sun is not understood but line_6: is a key to understanding internal mixing in cool stars. Alpha line_7: Centauri A and B will be measured to study mixing in stars respectively line_8: slightly more and less massive than the sun. Beta Hyi will be studied line_9: as an example of a 1.0 solar mass, partially evolved star. line_10: 2. The rates of mixing processes, especialy those which line_11: are expected to operate only on long timescales, will be studied by line_12: observing two stars in the intermediate age cluster NGC 752. One star line_13: will be from inside the "Lithium Gap" region in the F stars, and one line_14: star from outside the gap. line_15: 3. Two red giants and subgiants will be observed to help measure the line_16: amount of mass lost on the giant branch. line_17: . . . . . . . . . . . . . . . . . . . . . . line_18: NOTE: THIS PROPOSAL ONLY USES SIDE 2 OF THE GHRS. We are aware of line_19: the GHRS condition (as the P.I. is GHRS Instrument Scientist.) ! ! end of abstract general_form_proposers: lname: DUNCAN fname: DOUGLAS title: PI mi: K inst: SPACE TELESCOPE SCIENCE INSTITUTE country: USA ! lname: PINSONNEAULT fname: MARC mi: H. inst: YALE UNIV. country: USA ! lname: DELIYANNIS fname: CONSTANTINE mi: P. inst: YALE UNIV./UNIV.

All ONBOARD ACQs; all are single stars. line_3: Almost all of the targets are BRIGHT, and RETURN TO BRIGHTEST line_4: POINT IS ESSENTIAL for the target acquisition to work. ! question: 4 section: 0 line_1: Boron 2500A cannot be observed from the ground. Can't get line_2: nearly enough S/N with IUE. Be 3130 can be marginally observed line_3: from the ground, but high accuracy is extremely difficult line_4: on faint objects. ! question: 5 section: 0 line_1: Not Needed. ! question: 6 section: 0 line_1: Not needed. ! question: 7 section: 0 line_1: Duncan has extensive STSDAS/IRAF experience, and the ability to line_2: reduce GHRS data. He has done spectrum synthesis work, using the latest line_3: synthesis program and atmospheres of Kurucz (1990, private comm.), line_4: This work takes time; thus the budget request for 18 months support. line_5: The paper on Boron in Three Halo stars just sent to Ap. J (Duncan, line_6: Lambert, and Lemke) shows a very successful analysis of exactly line_7: the kind required here. The stellar structure models are an line_8: additional phase beyond data reduction per se. These have been line_9: done successfully in the past by the Co-I's at Yale. There is line_10: some computer support money in the budget for this. ! question: 8 section: 0 line_1: None. ! question: 9 section: 0 line_1: Prop. 2634. Duncan, P.I. "Boron and Be as probes of Cosmic Ray line_2: Spallation." Three spectra obtained, fully reduced, compared to line_3: synthetic spectra. Paper written; will be submitted to Ap. J. line_4: shortly. Co- authors David Lambert and Michael Lemke. A second line_5: paper should follow additional observations. line_6: Prop. 2619. "Precision Parallaxes of Cepheids... with WF/PC." line_7: No data yet.
