ROSAT observations of PSR 2334+61 in the supernova remnant G114.3+0.3

Original · EN

We report on the observation of PSR 2334+61 in the soft X-ray domain with ROSAT. Assuming a power-law spectrum dN/dE∝ E⁻α with photon-index α=2 we derive an X-ray flux of fₓ=(7.1 ± 0.2) × 10⁻¹⁴ erg s⁻¹cm⁻² within the 0.1--2.4 keV energy range. An upper limit for the neutron star's surface temperature is put at Tₛ∞ 1.2× 10⁶ K for a neutron star with a medium stiff equation of state (FP-model with M=1.4, R=10.85 km). Slightly different values for Tₛ∞ are computed for the various neutron star models available in the literature, reflecting differences in the equation of state. No soft X-ray emission is detected from the supernova remnant G114.3+0.3 associated with PSR 2334+61.
