abstract:

    line_1:        By obtaining high resolution, high S/N profiles of the transition region line
    line_2:        in an active chromosphere star, it is possible to apply Doppler Imaging
    line_3:        techniques in order to map the surface plages. We propose to obtain 8 spectra
    line_4:        of C IV and Mg II lines in AR Lac, spaced around the orbit, to determine the
    line_5:        spatial location of the active regions in the transition regions and lower
    line_6:        chromspheres of the two stars.

  question:        3
    section:       1
    line_1:        All 8 exposures must occur within one orbital period (47h36m) at about 5.5 hour
    line_2:        intervals to obtain uniform phase coverage.
    line_4:        These observations should be scheduled for cycle 1.

!

  question:        4
    section:       1
    line_1:        C IV and Mg II lie in the vacuum UV, and are inaccessible from the ground.

!

  question:        5
    section:       1
    line_1:        To obtain uniform phase coverage and minimize the effects of secular
    line_2:        variability, all 8 exposures must occur within one orbital period (47h36m), at
    line_3:        about 5 hour intervals.

!

  question:        7
    section:       1
    line_1:        Data will be reduced and analyzed at SUNY using existing spectroscopic
    line_2:        software.

!

  question:        8
    section:       1
    line_1:        We will arrange for simultaneous ground based photometry and with enough lead
    line_2:        time, will attempt to obtain coverage at other frequencies (i.e., VLA or
    line_3:        optical).

!

  question:        10
    section:       1
    line_1:        SUNY will supply the data analysis capability for the scientific analysis.

!

  question:        12
    section:       1
    line_1:        Estimated observing time includes 5m for target acquisition for the first pair
    line_2:        of observations only, and all HRS internal overhead.
    line_4:        I estimate acquisition time for subsequent acquisitions to be the peakup time
    line_5:        (96s). Overhead assumes 20s for Y-balance, 30s for carrousel settling, and 4s
    line_6:        for readout at each grating position, as well as 2m for carrousel stowaqe.

!

  question:        13
    section:       1
    line_1:        We shall obtain high S/N, high resolution C IV and Mg II line profiles spaced
    line_2:        around one orbit of AR Lac, in order perform a Doppler Imaging analysis to
    line_3:        determine the spatial scales and ingomogeneities in the lower chromosphere and
    line_4:        the transition region.
