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 1 early-type star in
    line_3:        the galactic disk using the Goddard High Resolution Spectrograph
    line_4:        to obtain precise measures in the ultraviolet with the highest available
    line_5:        spectral 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 such
    line_8:        clouds and the various physical processes occurring vary with cloud
    line_9:        parameters such as H column density, velocity, ionization level, and
    line_10:       distance z from the galactic plane.  This information should help to
    line_11:       clarify the many physical processes occurring in interstellar gas.
    line_12:       The program should also increase our understanding of the balance
    line_13:       between formation and destruction of interstellar dust grains.

  question:        3
    section:       1
    line_1:        The observations planned during Cycle 4, and supported with GO/DD time,
    line_2:        will in general follow the pattern set for our ongoing GTO program,
    line_3:        ID 1071.  A series of interstellar absorption lines longward of
    line_4:        1800 A will be observed with Echelle B of the GHRS,
    line_5:        giving the highest resolution available (resolving power R about
    line_6:        85,000) for lines of S I, Si II, Mg I, Fe II, Co II, Cr II, Zn II, and
    line_7:        Mn II.  For photometric accuracy, the FP-SPLIT mode is used to give
    line_8:        four adjacent exposures of each line.  Another series of lines at
    line_9:        shorter wavelengths, between 1120 and 1600 A, will be observed with the
    line_10:       GHRS grating G160M, again using the FP-SPLIT routine to obtain four
    line_11:       adjacent subexposures.  These shorter wavelength observations will
    line_12:       be performed using Echelle A if the GHRS Side 1 becomes available
    line_13:       during Cycle 4.  Of the many interstellar lines in this region the
    line_16:       following species are of particular interest:  C I, C II, CIV, N I, N V,
    line_17:       O I, Mg II, S II, S III, Si II, Si III, Si IV, P II, PIII, Fe II, and
    line_18:       Mn II. While the resolving power with the G160M grating is in the range
    line_19:       from about 15,000 to 24,000, deconvolution of each spectrum may almost
    line_20:       double the effective R.  For accurate wavelength calibration, exposures
    line_21:       of the calibration lamp spectrum will be taken at the beginning and
    line_22:       end 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:        9
    section:       1
    line_1:        PREVIOUS HST PROGRAMS: GTO 1071, 3215, and AUG 3444 "Composition of
    line_2:        Gas in Individual Interstellar Clouds".  These identification numbers,
    line_3:        for observations in Cycles 0, 1, and 2, designate the ongoing project
    line_4:        for which the present proposal represents Director's Discretionary
    line_5:        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
    line_10:       new strategy for removing the effects of scattered light from GHRS
    line_11:       echelle data and a very effective technique for correcting for fixed
    line_12:       pattern noise in the data, an effect important for the brighter stars,
    line_13:       for which S/N can be about 100 or more.  In the halo star HD93521,
    line_14:       1500 pc from the galactic plane, the observed widths of the
    line_15:       C IV and Si IV absorption features are 50 km/sec (FWHM), as compared
    line_16:       with 7 km/sec for a narrow S II component.  Measures of the
    line_17:       low-ionization lines (such as S II, Si II, Fe II) have given detailed
    line_18:       information on the depletion of elements from the gas as a result
    line_19:       of condensation on solid grains, and suggest that iron orthosilicate
    line_20:       is a primary constituent of these grains.  The temperature and density
    line_21:       of the interstellar gas have also been determined.

  question:        9
    section:       2
    line_1:        PUBLICATIONS RESULTING FROM THE ABOVE DATA:  A brief description of
    line_2:        these data and of their technical aspects has appeared in the STScI
    line_3:        Newsletter, June 1991 (Vol. 8, No. 2).  The observed profiles of the
    line_4:        C IV and Si IV features in HD93521 are presented in Ap.J. Letters
    line_5:        (May 10, 1992), and their possible interpretation discussed.  A full
    line_6:        discussion of the HD 93521 results appears in the Ap.J. (May 20,
    line_7:        1993).

  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:        now Research Astronomer with continuing appointment.  The Department
    line_6:        of Astrophysical Sciences contributed funds toward his salary
    line_7:        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.
