abstract:

    line_1:        We propose to observe boron in late type stars of metallicities ranging
    line_2:        from disk to extreme halo and combine this data with our ground-based
    line_3:        measurements of Be and Li.  The evolution of Li, Be, and B has now been
    line_4:        shown to be a powerful descriminant between different models of the chemical
    line_5:        and dynamical evolution of the galaxy, and must be added to the evolution of
    line_6:        \[Fe/H\] and \[O/H\] as the critical test of such models. Light element
    line_7:        production depends on the intensity and shape of the cosmic ray spectrum, which
    line_8:        in turn depends on the supernova rate and thus the star formation rate. It also
    line_9:        depends on the rise of the (progenitor) CNO abundances, and the decline of
    line_10:       the gas mass fraction, which is affected by rates of infall of fresh
    line_11:       (unprocessed) material and outflow, e.g. by supernova heating. By concentrating
    line_12:       on stars at the transition from old disk to halo and in the halo population
    line_13:       we can learn the most about the importance of each of these critcal properties
    line_14:       of the early galaxy. Already the first 3 HST observations of B in halo stars
    line_15:       CANNOT be matched by existing models of galactic chemical evolution (4).
    line_16:       -- In addition, the search for primordial B and Be in the most metal-poor
    line_17:       stars is the key for discriminating between standard and inhomogeneous big
    line_18:       bang nucleosynthesis models. Some recent evidence hints at inconsistancy
    line_19:       in the standard model, and accurate observations of B and Be are critical
    line_20:       to test and constrain the various inhomogeneous models.

  question:        3
    section:       1
    line_1:        A single GHRS observation will be made of each star, using the G270M grating
    line_2:        centered  at 2500A, the wavelength of the B resonance lines.  The same
    line_3:        techniques (FP-SPLIT, the best vignetting corrections, etc.) used for achieving
    line_4:        the highest S/N on weak features which were successfully used to observe the
    line_5:        first three halo stars (Duncan, Lambert, and Lemke, CYCLE 1) will be used.
    line_6:        The new SSA ACQ/PEAKUP capability is requested for better efficiency.

  question:        4
    section:       1
    line_1:        The only boron lines suitable for late-type stars are in the UV (2500A)
    line_2:        and cannot be observed from the ground, or with enough resolution with IUE.

!

  question:        4
    section:       2
    line_1:        [The PI is former GHRS Instrument Scientist.]  Count rates are scaled from:
    line_2:        Count rates observed (by PI) in HD 140283, a halo star of similar spectral
    line_3:        type, observed with exactly the same GHRS setup. Allowance was made for the
    line_4:        dependence of the UV flux on the slightly different effective temperatures
    line_5:        of our stars.

  question:        6
    section:       1
    line_1:        An extra comparison or standard star is being requested to aid in the model
    line_2:        atmosphere analysis.  We have deliberately left 2.17 hours for this, so the
    line_3:        RPSS RESOURCE ESTIMATE submitted is LOW. We will request this extra target
    line_4:        on a separate "STScI Change Request Form."

  question:        7
    section:       1
    line_1:        Duncan has extensive STSDAS/IRAF experience, and the ability to reduce the
    line_2:        data at U.Chicago.  Also, he has already done successful specrtum synthesis
    line_3:        work, using the latest synthesis program and atmospheres of Kurucz (1991,
    line_4:        private communication), essential for determining accurate B abundances.
    line_5:        From the analysis of 3 metal-poor stars in Cycle 0, a good line-list and
    line_6:        suitable programs are ready and waiting to be applied to the new stars.
    line_7:        HOWEVER, the more metal-rich stars are more difficult to analyze, having
    line_8:        many, many more lines.  We will add one standard star, of very well known
    line_9:        composition, to help make an empirical comparison.  Considerable time will
    line_10:       be required to make a careful anaysis of the data, even though we have
    line_11:       the facilities.
