SUMMARY OF SEQUENCE NUMBER 400023
Title: THE BINARY MS-PULSAR PSR J0218+4232 AND ITS PROBABLE SYNCHROTRON NEBULA
Observer: Kuiper
Subject Category: BH and NS Binaries
Seq: 400023 ObsId: 00656
Long-term Plan bin: 22-Dec-1999
ABSTRACT
In a recent 100 ks ROSAT HRI observation of the binary ms-pulsar PSR J0218+4232 we detected a lightcurve with two narrow pulses; the measured width of the main pulse (350 microsec) is compatible with the scatter in the ROSAT clock. About 60% of the emission is unpulsed and can be explained by emission from a compact nebula with diameter ~14'', compatible with available radio data. Only AXAF's HRC-I can disentangle the spatial emission, as well as resolve the narrow structures in the lightcurve; a 75 ks observation suffices. We further propose a spectral study of this ms-pulsar and its probable synchrotron nebula with AXAF's ACIS-I detector (100 ks) in order to investigate the underlying production processes.
