SUMMARY OF SEQUENCE NUMBER 500014
Title: THE VELA PULSAR
Observer: FEIGELSON
Subject Category: SN, SNR, and isolated NS
Seq: 500014 ObsId: 00127
Long-term Plan bin: 24-Jan-2000
ABSTRACT
The pulsar PSR B0833-45 inside the Vela supernova remnant is the youngest and brightest source of thermal X-ray radiation from a neutron star. It thus provides an important laboratory for study of several expected components: continuous soft thermal X-ray emission from the cooling neutron star surface, pulsed hard thermal X-rays from the hot magnetic polar caps, and absorption features from the highly magnetized atmosphere. This observation will resolve the Vela pulsar from the surrounding synchrotron nebula, and give a high resolution spectrum that may reveal the chemical composition of its outer layers, its surface magnetic field, mass/radius ratio, and polar cap properties. The HRC detector is used to obtain spectra at different phases within the 89 ms rotational period.
