Principal Investigator Institution Country Telephone J. chris Blades SPACE TELESCOPE SCIENCE INST USA (410)338-4805 DR. ------------------------------------------------------------------------------------ 7. Abstract Using the high resolution f/96 mode of the FOC we shall image Magellanic Cloud Planetary Nebulae - objects whose diameters are less than 2 arcsec. Their known distances will allow nebular masses to be derived from their angular diameters, yielding the distribution of PN shell masses for the first time. In combination with their nebular expansion velocities, known from ground-based studies, it will be possible to determine the age of the objects. ------------------------------------------------------------------------------------ 8.

STSDAS/IRAF tools ------------------------------------------------------------------------------------ 8. Additional comments or special requests. N/A ------------------------------------------------------------------------------------ 9. Description of previous HST work. Four planetary nebulae were previously observed in the Magellanic Clouds: SMC N2, SMC N5, LMC N66 and LMC N201. Each were observed in both the F501N and F486N filters. ------------------------------------------------------------------------------------ 10. Resources to be supplied by investigator's institution(s). Supported by FOC NASA grant. ------------------------------------------------------------------------------------ 13. We shall carry out high resolution imaging of Magellanic Cloud Planetary Nebulae to determine their masses and ages. ------------------------------------------------------------------------------------ 11.
