abstract:

    line_1:        Almost all studies of short-period RR Lyrae stars have mentioned the
    line_2:        possibility of small-scale fluctuations in light curves or short time-scale
    line_3:        changes in absorption line strengths. While careful examination of high
    line_4:        signal-to-noise ratio visible light curves has failed to confirm such behavior,
    line_5:        fluctuations may still be detectable in the ultraviolet region. These would
    line_6:        reflect such phenomena as shock waves generated by the pulsation in the outer
    line_7:        stellar envelope. We propose high time resolution, high signal-to noise ratio
    line_8:        observations of a sample of such stars to characterize the ultraviolet
    line_9:        pulsation and investigate the pulsation effects in the upper atmosphere.
    line_10:       Revision History: Received on RPS 9/1/89;  Added to SCCS 9/5/89
    line_11:       RPSS V7.2 remote & local; Small syntax errs fixed - SALM 9/14/89
    line_12:       Move 2 targ to cycle 2 - SALM 3/5/90; Added ANALOG datafmt - SALM 7/11/90;
    line_13:       Made changes re team meeting 7/18/90--BJW 7/23/90; Split proposal by cycle--
