abstract:

    line_1:        We will use the HST to survey the nuclear
    line_2:        regions of M83, a nearby barred spiral galaxy with
    line_3:        a starburst nucleus (Bohlin et al. 1983).

  question:        3
    section:       1
    line_1:        During Cycle 1, we will obtain U, R, H-alpha, and I-band
    line_2:        pictures of the nucleus of M83.
    line_3:        We will use these pictures choose the starburst areas for
    line_4:        observing in Cycle 2 (GTO augmentation time). We
    line_5:        will identify "blue" (starburst) regions by their colors,
    line_6:        while H-alpha will reveal H II regions near the nucleus.

  question:        4
    section:       1
    line_1:        The HST is necessary for access to the ultraviolet (where
    line_2:        the stellar wind features are found) at high angular
    line_3:        resolution.

!

  question:        7
    section:       1
    line_1:        The PC pictures will be used to construct a photometric and
    line_2:        astrometric map of the nuclear regions of M83. Subsequent
    line_3:        FOS spectra of selected nuclear starburst regions will be
    line_4:        analyzed in order to deduce the stellar content.

!

  question:        13
    section:       1
    line_1:        We propose to use the HST/PC and FOS to investigate the
    line_2:        nucleus of M83, a barred spiral galaxy whose nucleus has
    line_3:        both normal and starburst characteristics.
