I have edited postarg on exp 3 & 4, and restricted roll to 5-30, as Sylvia has recommended, -981988533 ----- Attempting Submission 1 (Thu Oct 15 23:54:11 GMT 2015) ----- ----- Attempting Submission 2 (Tue Oct 20 06:26:05 GMT 2015) ----- The nearby single millisecond pulsar J2124-3358 shows a unique Halpha bow shock around a swept-back, asymmetric X-ray trail. Our ACIS exposure measures fine structure near the pulsar, discerning the spin/polar jet axis from the equatorial torus. Spectra measure the PSR cap heating and PWN synchrotron cooling. A search for moving knots in the PWN can constrain the post-shock flow speed. Comparison with our ground optical imaging and spectroscopy measures the 3-D shock geometry and is enhanced by an HST Halpha image resolving the sub-arcsecond shock apex. These permit accurate modeling of the pulsar wind momentum distribution, a measurement of the pulsar moment of inertia and a novel test of the recycling+evaporation scenario for isolated millisecond pulsars. WFC3/UVIS exposures of a faint pulsar bow shock. 2600s F656N + 100s+F606W for each of two orbits. We will place the critical nebula apex near the read-out node and may post-flash for improved CTE. 12 false false false false SUPPORTED EXT-MEDIUM EMISSION LINE NEBULA YES Diffuse Halpha nebula J2000 J2000 1445322337990 C:\Users\rwr\AppData\Local\Temp\OPVisit8496095916610025301.xml The scheduling data was generated by CASM 23.2.
