abstract:

    line_1:        Column densities of interstellar atoms of 17 atomic species of 10
    line_2:        elements will be measured in the line-of-sight to 2 early-type stars,
    line_3:        using the Goddard High Resolution Spectrograph to obtain precise
    line_4:        measures in the ultraviolet with the highest available spectral
    line_5:        resolution.  These data will be analyzed to determine relative
    line_6:        abundances in the several individual clouds present along each line of
    line_7:        sight, and thus to determine how the composition of the gas in
    line_8:        such clouds and the various physical processes occurring vary with
    line_9:        cloud parameters such as H column density, velocity, ionization level,
    line_10:       and distance z from the galactic plane.  This information should help
    line_11:       to clarify the many physical processes occurring in interstellar gas.
    line_12:       In particular, measures of stars in the galactic halo should help to
    line_13:       identify the mechanisms responsible for the abundant C IV, Si IV, and N
    line_14:       V known to be present in the interstellar gas at kiloparsec distances
    line_15:       from the galactic plane.  The program should also increase our
    line_16:       understanding of the balance between formation and destruction of
    line_17:       interstellar dust grains.

  question:        3
    section:       1
    line_1:        The observations  of two stars planned during Cycle2, and supported
    line_2:        with GTO Augmentation time (under #3444), will in general follow the
    line_3:        pattern set for our one star to be observed in Cycle 1 (under #3215).
    line_4:        For each star, a series of interstellar absorption lines longward of
    line_5:        1800 A will be observed with Echelle B of the GHRS, giving the highest
    line_6:        resolution available (resolving power R about 85,000) for lines of S I,
    line_7:        Si II, Mg I, Fe II, Co II, Cr II, Zn II, and Mn II.  For photometric
    line_8:        accuracy, the WSCAN mode will be used to give three adjacent exposures
    line_9:        of each line.  Another series of lines at shorter wavelengths, between
    line_10:       1120 and 1600 A, will be observed with the GHRS grating G160M, using
    line_11:       the FP-SPLIT routine to obtain subexposures at four adjacent
    line_12:       wavelengths.  Of the many interstellar lines in this region the
    line_13:       following species are of particular interest:  C I, C II, C IV, N I,
    line_14:       N V, O I, Mg II, S II, S III, Si II, Si III, Si IV, P II, P III, Fe II,
    line_15:       and Mn II.  While the resolving power with this grating is in the range
    line_16:       from about 15,000 to 24,000, deconvolution of each spectrum may almost
    line_17:       double the effective R.  For accurate wavelength calibration, exposures
    line_18:       of the calibration lamp spectrum will be taken at the beginning and end
    line_19:       of each series.

  question:        4
    section:       1
    line_1:        Much pioneering work on individual interstellar clouds has been done
    line_2:        from the ground.  However, to obtain data on many elements, including
    line_3:        the highly ionized species, requires observations from above the
    line_4:        atmosphere.  The Copernicus satellite made important contributions to
    line_5:        this topic, but its resolving power of 20,000 was insufficient to
    line_6:        resolve clearly many of the individual components in most lines of
    line_7:        sight, although in favorable cases properties of individual clouds were
    line_8:        successfully deduced.  The IUE satellite has been enormously useful for
    line_9:        broad surveys of interstellar absorption, especially for the fainter
    line_10:       stars which could not be observed with Copernicus, but its resolving
    line_11:       power of 10,000 is inadequate for resolving most components.  The HST,
    line_12:       with its resolving power of 85,000 for lines observed with Echelle B, can
    line_13:       answer detailed questions on the physical properties of individual
    line_14:       clouds towards many stars.

  question:        7
    section:       1
    line_1:        To analyze the HST/GHRS data for this ongoing project, a dedicated Sun
    line_2:        SPARCstation 1 has been obtained.  This facility should be entirely
    line_3:        adequate for the processing and analysis af all the data.  The STSDAS
    line_4:        software (running as part of the IRAF system) and the IDL language have
    line_5:        both been implemented on the SPARCstation.
    line_7:        As part of the data processing, corrections will be made for a variety
    line_8:        of effects, including scattered light, fixed pattern noise, and shift
    line_9:        of wavelength calibration with temperature.  Data analysis will
    line_10:       determine for each line the function Nr(v), the apparent column density
    line_11:       of species r per unit velocity interval, as a function of Doppler-shift
    line_12:       velocity v.  Comparison of Nr(v) between lines of different f-values
    line_13:       but with the same lower state yields a correction of these values for
    line_14:       saturation, if the corrections are not large.

  question:        9
    section:       1
    line_1:        PREVIOUS HST PROGRAMS: GTO 1071, 3215, and 3266, "Composition of
    line_2:        Individual Interstellar Clouds".  These identification numbers, for
    line_3:        observations in Cycles 0, 1, and 2 or later, respectively, designate
    line_4:        the ongoing project for which the present proposal represents
    line_5:        Augmentation time.
    line_7:        MAIN RESULTS OBTAINED FROM PREVIOUS RELATED PROGRAMS:  Two stars, HD
    line_8:        68273 (Gamma-2 Velorum) and HD 93521, were observed for the program
    line_9:        GTO 1071 during Cycle 0.  Analysis of these data has yielded a significant
    line_10:       redetermination of the GHRS sensitivity as a function of wavelength in
    line_11:       the Echelle mode.  For example, the ratio of sensitivities at 1190 and
    line_12:       1300 A is only one-third of earlier estimates.  In addition, a new
    line_13:       program has been devised to correct for fixed pattern noise, an effect
    line_14:       important for the brighter stars, for which S/N can be about 100 or
    line_15:       more.  In the halo star HD93521, 1500 pc from the galactic plane, the
    line_16:       observed widths of the C IV and Si IV absorption features are 50 km/sec
    line_17:       (FWHM), as compared with 7 km/sec for a narrow S II component.
    line_19:       PUBLICATIONS RESULTING FROM THE ABOVE DATA:  A brief description of
    line_20:       these data and of their technical aspects has appeared in the STScI
    line_21:       Newsletter, June 1991 (Vol. 8, No. 2).  The observed profiles of the
    line_22:       C IV and Si IV features in HD93521 are presented in Ap.J. Letters (in
    line_23:       press, 1992), and their possible interpretation discusssed.

  question:        10
    section:       1
    line_1:        The participation of L. Spitzer, now Senior Research Astronomer at
    line_2:        Princeton University, is without charge to the Project; he expects to
    line_3:        devote nearly all his research time to this work.  The chief annual
    line_4:        cost to the Project is the full-time salary of E.L. Fitzpatrick,
    line_5:        recently promoted to a continuing appointment as Research Astronomer.
    line_6:        The Department of Astrophysical Sciences contributed funds toward his
    line_7:        salary during several years before full NASA funding (by subcontract
    line_8:        with O'Dell's home institution, the Rice University of Technology)
    line_9:        became available.  Computer peripherals, including tape drives and a
    line_10:       laser printer, are available at the Department for a small monthly
    line_11:       charge.
