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-- line_14: BJW 3/24/91; ! ! end of abstract general_form_proposers: lname: BLESS fname: ROBERT mi: C. inst: WISCONSIN, UNIVERSITY OF country: USA ! lname: VAN CITTERS fname: G. mi: W. inst: NATIONAL SCIENCE FOUNDATION country: USA ! lname: DOLAN fname: JOSEPH mi: F. inst: NASA, GODDARD SPACE FLIGHT CENTER country: USA ! lname: ELLIOT fname: JAMES mi: L. inst: MASSACHUSETTS INSTITUTE OF TECHNOLOGY country: USA ! lname: ROBINSON fname: EDWARD mi: L. inst: TEXAS, UNIVERSITY OF country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: Cycle 0 - One star (AI Vel) in or near continuous viewing zone if line_2: possible. line_4: Cycle 1 - All others. line_7: Total time: 9 hours 16 seconds line_9: High time resolution, high signal to noise ratio light curves of short period line_10: RR Lyrae stars will be obtained in both visible and ultraviolet wavelengths. line_11: The HSP/PRISM mode will be used at 5 second time resolution. ! question: 4 section: 1 line_1: See Section 2 ! question: 13 section: 1 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.
