Principal Investigator Institution Country Telephone Dr. Holland C. Ford SPACE TELESCOPE SCIENCE INST USA (410) 338-4803 ------------------------------------------------------------------------------------ 7. Abstract WF/PC interference filter pictures will be used to resolve the shells of planetary nebulae in the LMC and to resolve the shell of K648 in M15. The angular diameters of the shells will be combined with echelle expansion velocities to derive the ages of nebulae. Ultraviolet spectra of the central stars will be used to derive the stars' effective temperatures and magnitudes, with objective of placing the stars on evolutionary tracks in an M-Teff diagram. UV spectra of the LMC nebulae, K648, and the brightest nebula in M32, NGC205, and NGC185 will be used to derive chemical compositions and physical conditions in the nebulae. ------------------------------------------------------------------------------------ 8.

Cycle 3: 304-309 ------------------------------------------------------------------------------------ 5. Description of special scheduling requirements. The SV prerequisite programs for all FOS observations in this program are: Prop ID 2195 FOS Target Acquisition Tests - All observations Prop ID 1317 Int./Ext. Wavelength Offsets - 1st target Prop ID 1318 Spectral Flat Fields - 1st target Prop ID 1320 Absolute Spectrophotometry - 1st visit of bright targets All WF/PC imaging with a center wavelength blueward of 5000 Angstroms requires UV flood ------------------------------------------------------------------------------------ 12. The observations of the LMC planetaries constitute an integrated program to establish to evolution of central stars, and will not be complete until seven of the nine have been observed. Data should not be released until one year after completion of the seventh planetary nebula. Likewise, the three planetaries in NGC205, NGC185, and M32 constitute a program which will not be complete until two of the three planetaries have been observed. ------------------------------------------------------------------------------------ 13. WF/PC pictures of K648 and LMC planetaries will be used to resolve their shells. Small aperture FOS UV spectra of the central stars will be used to place the central stars on evolutionary tracks in an M-Teff diagram. Chemical composition and physical conditions in the shells will be derived from UV spectra of the nebulae. ------------------------------------------------------------------------------------ 11.
