SUMMARY OF SEQUENCE NUMBER 500047

Title: RADIO-SILENT NEUTRON STARS IN SUPERNOVA REMNANTS

Observer: PAVLOV

Subject Category: SN, SNR, and isolated NS

Seq: 500047 ObsId: 00751

Long-term Plan bin: 30-Dec-1999

ABSTRACT

The radio-silent neutron stars in SNRs, 1E 1207.4-5209 in PKS 1209-52 and RX J0821-4300 in Puppis A, provide unique opportunity to study cooling of young neutron stars and the properties of the superdense matter in their interiors. The ROSAT and ASCA observations of these objects have been interpreted in terms of neutron star atmosphere models. We propose AXAF observations to determine chemical composition, magnetic field and temperature of the atmospheres, to constrain the neutron star radius and mass, to search for so far unknown rotation periods and for putative compact nebulae around the neutron stars. We will also investigate the chemical composition, density, temperature and ionization state of the diffuse matter in the supernova remanants.
