Abstract The low frequency of occurrence of identified neutron stars located in supernova remnants (SNR's) is an unexplained embarassment to our generally accepted theories of stellar evolution and neutron star formation. We propose to search recent SNR's for any remnant star associated with them, and to study the photometric variability of known examples of neutron stars which are remnants of supernovae. The results will place important constraints on the mechanisms by which neutron stars originate.

Description of proposed observations. Searches for remnant stars at the center of recent SNR's would be conducted by the HSP in conjunction with the WFC and possibly the FOS. A WFC deep image of the SNR in the UV would reveal any suitably placed central images. These images would then be observed serially by the HSP in a wide bandwidth filter and the data analyzed for pulsation by fast Fourier transform methods. Observations in 3 different UV filters would allow the star to be plotted on a color-color diagram. Candidates with a hot color temperature or pulsation could be confirmed by an FOS spectrum. A neutron star spectrum would be expected to be a blue, featureless continuum a la the Crab nebula pulsar, but SS433 has a spectrum dominated by emission lines with relativistic velocity offsets and wavelength variations apparent from day to day. Hence, any candidate with an unusual spectrum would merit further study. Cycle 0 (SV/GTO) Observations: 1H 4M ------------------------------------------------------------------------------------ 4. Justification of need for HST observations. (1) remnant stars are known from presently available upper limits on most SNR central stars to be fainter than V = 20; searching for a fainter star requires the limiting magnitude available only on ST. (2) remnant stars are expected to have spectra which peak strongly in the UV. This wavelength region is available for faint objects only on ST. (3) one method of identifying remnant stars searches for their pulsational periods which are expected to be in the sub-second to second range. Freedom from noise induced by atmospheric scintillation makes the HSP the most efficient and sensitive instrument available to detect such periodicities. Page 3 ------------------------------------------------------------------------------------ 7. Data reduction and analysis plans. Deep images of SNR's in the UV will be analyzed to determine whether any suitably placed central images exist. The HSP photometric observations of these candidates will be analyzed by power spectrum analysis methods to determine if any pulsation exists (as it does in the Crab Nebula and 1E2259+586). Three filter photometry will be analyzed to determine the color temperature of the candidate in a color-color diagram; candidate stars with a hot color temperature will be confirmed by an FOS spectrum. Neutron star spectra are expected to be blue, featureless continua, as in the Crab Nebula, but SS433 has a spectrum dominated by emission lines with relativistic velocity offsets and wavelength variations apparent from day to day. Any candidate with an unusual spectrum will be studied further photometrically. Wide bandwidth photometric observations will be analyzed by power spectrum analysis methods for pulsation in the source. Photometric observations will also be analyzed for longer periodicities which may be present in the light curve. Concurrent polarimetric observations will also be searched for longer periodicities present in the source. The results will be applied to determining the location, geometry, and motion of the emitting regions. ------------------------------------------------------------------------------------ 12. Searching for the remnant stars in supernova remnants is directly related to Scientific Objective 2 specified in the HSP CEI specifications, "searches for optical counterparts to radio pulsars". This program is also related to Scientific Objective 5, "determination of the wavelength and time dependence of polarization in compact binaries, white dwarfs. . . etc.". ------------------------------------------------------------------------------------ 13. Recent supernova remnants will be searched for any remnant star associated with them. The photometric variability of neutron stars which are remnant stars of supernova explosions will be monitored. The results will be used to place constraints upon the mechanisms by which neutron stars can originate. ------------------------------------------------------------------------------------ 11.
