Abstract

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 f_x=(7.1 ± 0.2) × 10^-14 \hboxerg s^-1\hboxcm^-2 within the 0.1--2.4 keV energy range. An upper limit for the neutron star's surface temperature is put at T_s^∞ ∼ 1.2× 10⁶ K for a neutron star with a medium stiff equation of state (FP-model with M=1.4 \Mo, R=10.85 km). Slightly different values for T_s^∞ 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.
