Title: A STUDY OF ANOMALOUS X-RAY PULSARS

Observer: WEISSKOPF

Subject Category: SN, SNR, and isolated NS

Long-term Plan bin: no LTS bin

ABSTRACT

The 'anomalous' X-ray pulsars are a small group of very young X-ray pulsars whose properties (period distribution, X-ray spectra, associations with supernova remnants, no evidence for binarity) are strikingly different from those of normal binary X-ray pulsars. Their similarities to soft gamma repeaters supports the idea that they are strongly magnetized (10^14 G) solitary neutron stars ('magnetars'). We propose to make AXAF observations to search for small plerions around them, and to establish the presence of blackbody-like emission from the neutron star surface, both of which would provide strong evidence for the magnetar model.
