Two SNRs in M33 will be observed to study line_7: abundances and abundance gradients of elements not readily available from line_8: optical spectra and that are too faint for IUE. An oxygen-rich SNR in NGC 4449 line_9: will be observed, taking advantage of the small FOS slits to isolate the SNR line_10: from surrounding H II emission. ! ! end of abstract general_form_proposers: lname: BEAVER fname: EDWARD inst: UC, SAN DIEGO country: USA ! lname: BURBIDGE fname: E.

It will be necessary, therefore, to obtain short WFC line_3: exposures to permit exact positions for the FOS aperture to be chosen. The line_4: slit positions relative to offset stars (also chosen from the WFC images) will line_5: be measured and the FOS will be positioned by blind offset. A similar technique line_6: will be used to place a smaller FOS slit on the SNR in NGC4449. The M33 SNRs line_7: are distant enough and their positions are known well enough that no WFC line_8: exposures are needed. Blind offsets from nearby stars (chosen from existing line_9: CCD images will be sufficient to place the FOS aperture on these objects. line_10: Each object will be observed with a sequence of gratings providing coverage line_11: from 1150-6800 A (thus overlapping with existing optical data). line_12: Cycle 1 4.1 hours primary, 0 hours parallel line_13: Cycle 2 6.9 hours primary, 0 hours parallel line_14: Cycle 3 1.9 hours primary, 0 hours parallel ! question: 5 section: 1 line_1: The SV prerequisite programs for all FOS observations in this line_2: program are: line_3: Prop ID 2195 FOS Target Acquisition Tests All observations line_4: Prop ID 1317 Int./Ext.

The other objects are interesting each in their own right, and line_4: while comparison of one object to another will be useful, the observations of line_5: each object define a viable investigation. ! question: 13 section: 1 line_1: UV and optical spectra of six extragalactic supernova remnants will be line_2: used to study a number of problems relating to abundances, interstellar medium line_3: properties, nucleosynthesis, grain destruction and physical conditions in the line_4: remnant shocks. Observations will be concentrated in the LMC and M33, although line_5: the oxygen-rich remnant in NGC 4449 will also be observed. ! !end of general form text general_form_address: lname: DAVIDSEN fname: ARTHUR mi: F. category: PI inst: JOHNS HOPKINS UNIVERSITY addr_1: CENTER FOR ASTROPHYSICAL SCIENCES city: BALTIMORE state: MD zip: 21218 country: USA ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: N49 descr_1: SUPERNOVA REMNANT IN THE LMC pos_1: RA = 05H 25M 57S +/- 1S, pos_2: DEC = -66D 07' 32" +/- 5" equinox: 1950 fluxnum_1: 1 fluxval_1: SURF(4861) = 4.7 +/- 2.0 E-15 ! targnum: 14 name_1: NGC4449-SNR descr_1: OXYGEN-RICH SNR IN NGC4449 pos_1: RA = 12H 25M 44.8S +/- 0.2S, pos_2: DEC = 44D 23M 23.3" +/- 1" equinox: 1950 fluxnum_1: 1 fluxval_1: F-LINE(5007)=1.3 +/- 0.3 E-15, fluxval_2: W-LINE(5007)= 110 +/- 5 ! ! end of fixed targets !
