abstract:

    line_1:        Elemental abundances and the enrichment of interstellar gas are a strong
    line_2:        function of the processes associated with the broad spectrum of stellar
    line_3:        evolution. Stellar evolution theory predicts that specific elements can
    line_4:        have dramatically different nucleosynthetic histories and so studying
    line_5:        the gas phase abundances of such elements in both the Milky Way and
    line_6:        other galaxies provides important information on both stellar and
    line_7:        subsequently galactic evolution.  We propose a study to produce high
    line_8:        quality abundance data for the undepleted heavy element Kr (Z = 36)
    line_9:        toward six stars representing three distinctly different galactic
    line_10:       directions. Our main focus here is the abundance of Kr I  primarily
    line_11:       because it is a noble gas and is therefore not expected to be depleted
    line_12:       onto dust.  Thus, unlike all other heavier-than-Zn elements, measures
    line_13:       of Kr constitute a direct probe of the cosmic abundance.  Variability
    line_14:       in the abundance of Kr therefore yields a direct probe of
    line_15:       nucleosynthetic enrichment and the efficiency with which this material
    line_16:       is mixed in the interstellar gas.

  question:        3
    section:       1
    line_1:        We propose to observed 6 stars at the principal wavelength 1246 using
    line_2:        grating G160M. All observations will be made using the SSA and a
    line_3:        sampling strategy of four substeps per diode. The requested observations
    line_4:        will allow us to obtain high quality data for Ge II 1237.1 and Kr I
    line_5:        1235.8.  In addition, the wavelength coverage afforded by G160M will
    line_6:        also give us good data for the weak doublet of Mg II 1239.9,1240.4 and
    line_7:        other diagnostic lines down to 1264.  Since the lines we desire to
    line_8:        observe will be relatively  weak, we require high signal-to-noise data
    line_9:        which can be easily obtained using G160M and the SSA.  In order to
    line_10:       achieve this, each requested observation will employ the command
    line_11:       FP-SPLIT=4.   Also, since our program stars are bright, we must split
    line_12:       out observations into a suitable number of subexposures so as to not
    line_13:       overflow the maximum count of 65,536 per accumulation bin.
