Abstract In spite of extensive efforts only two definite (Crab and Vela) and one probable (in SNR 0540-693) radio pulsars have been detected at optical wavelengths. Only the Crab Pulsar has been observed in the ultraviolet. Most efforts at modeling the optical emission mechanism are constrained only by the Crab Pulsar observations. To provide better model constraints, visual and ultraviolet observations of the Crab, Vela, and LMC pulsars will be obtained. Likely candidates will also be observed to attempt detection of pulses from pulsars previously undetected in the optical (millisecond pulsars and two binary pulsars).

Robinson TEXAS, UNIVERSITY OF USA ------------------------------------------------------------------------------------ 3. Description of proposed observations. CYCLE 0: Crab Pulsar - Observe through UV and V filter each orbit to use V filter as phase reference. Total time 20 minutes each UV filter and 60 minutes in V--total 3H 2M. CYCLE 1: Vela Pulsar - WFC image(10M) 2 months before to identify field. One hour in each filter (3 filters) in rotation. Repeat until 4 hours of integration per filter are obtained. 12H 11M total. Vela may be in CVZ--needs dark time. LMC Pulsar - Same as Vela. Needs dark time. Millisecond Pulsars - WFC image 2 months before to explore field. Integrate for 5-1/3 hours in split mode (filters 750W & 320N) for each of two pulsar fields. Other Candidates Needs dark time. 16 hours total. ------------------------------------------------------------------------------------ 4. Justification of need for HST observations. The Space Telescope, besides the obvious access to the UV, provides an opportunity to examine pulse shape, phase as a function of frequency, and polarization with lower sky background levels, better discrimination against nebular contamination and lack of scintillation noise. Significant improvement over ground-based data is expected. ------------------------------------------------------------------------------------ 6. Description of special calibration exposures. Relating Space Telescope observations of pulsars to previous ground-based data will, in some cases, require calibration of the Space Telescope clock to +/- 10 msec to enable phase comparisons. This can be done after the observations. ------------------------------------------------------------------------------------ 13. To provide better model constraints, visual and ultraviolet observations of the Crab, Vela, and LMC pulsars will be obtained. Likely candidates will also be observed to attempt detection of pulses from pulsars previously undetected in the optical (millisecond pulsars and two binary pulsars). ------------------------------------------------------------------------------------ 11.
