abstract:

    line_1:        We shall obtain UV line fluxes and selected line profiles,
    line_2:        using the HRS, for another pre-main sequence
    line_3:        star. We are studying the atmospheric heating,
    line_4:        dynamics, and density structure of these stars.

  question:        3
    section:       1
    line_1:        All targets will be observed with the HRS through the large aperture. There
    line_2:        will be no explicit background observations, or comb-addition. The spectrum
    line_3:        will be half-stepped. The long integrations have been broken up into repeated
    line_4:        shorter exposures because of the lack of intermediate readout capability.
    line_5:        Specific wavelengths and exposure times are on the exposure log sheets.

!

  question:        4
    section:       1
    line_1:        Most chromospheric, and all transition region lines, lie in the far UV, and are
    line_2:        inaccessible from the ground. IUE observations have had limited success due to
    line_3:        the faintness of these objects and the resulting low S/N.

!

  question:        7
    section:       1
    line_1:        The data will reduced using standard spectroscopic analysis routines. The
    line_2:        resulting line fluxes will be used to determine the emission measure
    line_3:        distributions and the atmospheric structure.

  question:        10
    section:       1
    line_1:        SUNY shall supply office space and electricity in support
    line_2:        of the scientific analysis of these data.

!

  question:        13
    section:       1
    line_1:        This is a continuation of our cycle 2 program to study the
    line_2:        atmospheric structure of pre-main sequence stars, by
    line_3:        obtaining UV line fluxes and selected line profiles of
    line_4:        chromospheric and transition region lines. We will observe
    line_5:        another of our original sample of 6 PMS stars in this cycle.
