abstract:

    line_1:        We propose to observe a comprehensive sample of Wolf-Rayet (W-R) galaxies
    line_2:        --- starburst galaxies in which broad 4686 He II emission of stellar
    line_3:        origin has been detected. These galaxies generally contain far more W-R
    line_4:        stars than the Milky Way, M31, and other normal galaxies. The ultraviolet
    line_5:        FOC images and FOS spectra will be combined with optical and infrared
    line_6:        data as part of a large effort to perform a broad, systematic analysis
    line_7:        of the properties of W-R galaxies. The UV data obtained with HST will
    line_8:        provide crucial constraints on the hot star (O and W-R) populations, and
    line_9:        will lead to a better understanding of the physical conditions, initial
    line_10:       mass functions, and starburst parameters of these galaxies. The overall
    line_11:       continuum will be analyzed within the framework of evolutionary and
    line_12:       spectral synthesis models that we are developing. Quantitative
    line_13:       spectroscopy of UV resonance lines will allow us to study the hot star
    line_14:       populations in detail, and to directly measure the number of OB stars
    line_15:       within these galaxies. Our main goal is to determine which physical
    line_16:       properties of W-R galaxies (e.g., IMF slope, chemical composition, age,
    line_17:       strength and duration of the starburst) have led to the production of
    line_18:       large numbers of W-R stars. The results of this study will have
    line_19:       important implications for our understanding of W-R galaxies, and also
    line_20:       of starburst and emission-line galaxies in general.

  question:        3
    section:       1
    line_1:        We would like to obtain FOS spectra of the brightest knots of
    line_2:        some W-R galaxies. The objects were selected on the basis of the FOC
    line_3:        data from another proposal; There may be more than one knot per galaxy.
    line_4:        The scientific goal can be best achieved with the FOS and gratings
    line_5:        G130H and G190H. We intend to use the blue-side detector for both
    line_6:        gratings.  A peak-up technique is used for the TA.

!

  question:        4
    section:       1
    line_1:        It is the combination of the superior resolution (IUE: 6A; FOS: 3A for
    line_2:        a knot of 2-3") and vastly better S/N (IUE: typically 10; FOS: 35 for
    line_3:        our proposed observations) of HST data which provide a dramatic
    line_4:        improvement. STRONG lines (like C IV) can be modeled quantitatively
    line_5:        with HST, and WEAKER lines (like N IV 1718, which is an important
    line_6:        signature of hot EVOLVED stars) can only be detected with HST, in
    line_7:        contrast to IUE.

!

  question:        6
    section:       1
    line_1:        No special calibrations are requested. According to the FOC instrument
    line_2:        scientist, PSF's will be provided by STScI.

!

  question:        7
    section:       1
    line_1:        The general management of the observations (including the ground
    line_2:        observations) and the data reduction and interpretation will be
    line_3:        coordinated by Peter Conti.
    line_4:        FOS deconvolution will be carried out by Claus Leitherer. P. Conti is
    line_5:        also in charge of the pre-analysis of the HST observations (line
    line_6:        identification, interstellar extinction...). Other observations from
    line_7:        the ground are to be acquired, reduced and analysed by Alex Filippenko,
    line_8:        Wal Sargent and Bill Vacca.
    line_9:        The population synthesis models will be done at STScI by Carmelle
    line_10:       Robert and Claus Leitherer. All co-Is will be intimately involved with
    line_11:       data analysis and interpretation.

!

  question:        8
    section:       1
    line_1:        The HST observations are supported by ground-based observations. There
    line_2:        is no need for simultaneous observations.
