abstract:

    line_1:        The classical nova DQ Her is the prototype of the dust-forming novae with the
    line_2:        1934 ejecta well resolved on the sky providing an emission line spectrum
    line_3:        corresponding to an electron temperature of just T ~ 500K.
    line_4:        WF/PC images of the shell will be obtained to study the nebular dust and gas.

  question:        3
    section:       1
    line_1:        A WFC image of DQ-Her in the broad 'V' (dominated by H-alpha line emission
    line_2:        from the shell) is to be obtained.
    line_3:        The WFC image is also to serve as an early acquisition
    line_4:        exposure for FOS/G160L exposures of selected knots in the
    line_5:        nebula.

!

  question:        4
    section:       1
    line_1:        The ultraviolet is essential for key lines and the scattered continuum
    line_2:        contributed by the higher scattering cross-section of dust grains in DQ Her's
    line_3:        nebula. HST also provides the higher spatial resolution needed to resolve fine
    line_4:        filamentary structure.

!

  question:        7
    section:       1
    line_1:        Spectra as reduced by the standard STScI software will be analyzed at the
    line_2:        University of Texas. WF/PC images will probably be handled at STScI.
    line_4:        Interpretation will be integrated with our present work on DQ Her and related
    line_5:        old novae.

  question:        10

  question:        13
    section:       1
    line_1:        Ultraviolet spectra and images of the DQ Her's nebula will provide information
    line_2:        on the gas and dust content of the cool ejecta from the 1934 outburst.
