abstract:

    line_1:        Almost all studies of short-period RR Lyrae stars
    line_2:        have mentioned the possibility of small-scale
    line_3:        fluctuations in light curves or short time-scale
    line_4:        changes in absorption line strengths. While careful
    line_5:        examination of high signal-to-noise ratio visible
    line_6:        light curves has failed to confirm such behavior,
    line_7:        fluctuations may still be detectable in the
    line_8:        ultraviolet region. These would reflect such
    line_9:        phenomena as shock waves generated by the pulsation
    line_10:       in the outer stellar envelope. We propose high time
    line_11:       resolution, high signal-to noise ratio observations
    line_12:       of a sample of such stars to characterize the
    line_13:       ultraviolet pulsation and investigate the pulsation
    line_14:       effects in the upper atmosphere.  Revision History:
    line_15:       Defer to Cycle 2--BJW 12/24/91; Added comment lines
    line_16:       concerning deferment of test until PRISM mode
    line_17:       calibration--BJW 3/18/92; Changed ACQ detector from
    line_18:       VIS to UV1--BJW 1/21/93;
