Principal Investigator Institution Country Telephone Robert C. Bless WISCONSIN, UNIVERSITY OF USA (608)262-1715 ------------------------------------------------------------------------------------ 7. Abstract Some of the most luminous and massive stars in our galaxy and in the Large Magellanic Cloud will be monitored for variability in light. Knowledge of the time scales and amplitudes of luminosity fluctuations can perhaps place useful constraints on various stellar models.

White SPACE TELESCOPE SCIENCE USA INSTITUTE G. W. Van Citters NATIONAL SCIENCE FOUNDATION USA ------------------------------------------------------------------------------------ 3. Description of proposed observations. All of the objects on the target list will be monitored for 30 minutes each on two occasions separated by a few days. Photometry will be done with the beam splitter on UV2 (F145M and F262M). These observations are to be carried out in Cycle 1. ------------------------------------------------------------------------------------ 4. Justification of need for HST observations. ST is required in order to observe in crowded fields and in the ultraviolet where the luminosity variations are expected to be larger. ------------------------------------------------------------------------------------ 13. Some of the most luminous stars in the Milky Way and in the Large Magellanic Cloud will be monitored to determine the amplitude and time scales of their luminosity variations. ------------------------------------------------------------------------------------ 11.
