| Abstract: |
The X-ray nebula associated with the nova shell of GK Persei (1901) is lumpy and asymmetric with most of the emission coming from the SW. The brightest X-ray emission region that appears as an arc is co-spatial with the brightest non-thermal radio emitting region and found to be a source of non-thermal X-ray emission with a power law photon index of 2.3+0.9−1.3 with L ~ 4 × 1030 erg s−1 at 470 pc. The unexpectedly low temperature of the forward shock (0.1-0.3 keV) is suggestive of particle acceleration occurring in this region, too. The total X-ray spectrum of the nebula consists of two prominent components of emission (other than the localized non-thermal emission). |
