An X-ray pulsar in SNR G109.1–1.0

Nature volume 293, pages 202–204 (1981)Cite this article

Abstract

The unusual extended X-ray source G109.1–1.0 (ref. 1), discovered with the Einstein Observatory2, looks like a supernova remnant (SNR) and is of particular interest because it contains a point source 1E2259+586, from which a long curving arc of emission appears to extend, joining smoothly with the outer edge of the diffuse emission. We have now analysed the photon arrival times for the point source. (The point source was previously1,3 designated as GF2259+586; here we will use the 1E designation adopted by Tuohy and Garmire4.) We conclude that the point source is an X-ray pulsar.
