SUMMARY OF SEQUENCE NUMBER 500049

Title: AXAF OBSERVATIONS OF THE DUCK PULSAR PSR B1757-24

Observer: KASPI

Subject Category: SN, SNR, and isolated NS

Seq: 500049 ObsId: 00753

Long-term Plan bin: 12-Apr-2000

ABSTRACT

The young energetic radio pulsar PSR B1757-24 is traveling at high velocity out of the supernova remnant G5.4-1.2, in the process, re-energizing the remnant's shell, and powering a synchrotron nebula having dramatic bow-shock morphology. AXAF observations will determine properties of the pulsar wind that are unobservable in other systems, and permit detailed study of the unusual pulsar/remnant interaction. Useful X-ray observations of the PSR B1757-24/G5.4-1.2 system have been impossible before AXAF, because of the low predicted count rates for ROSAT, and because of a nearby unrelated bright source that contaminated the ASCA field. The first X-ray observation of this unique source has thus awaited the arrival of AXAF, with its high energy response, and unparalleled spatial resolution.
