Scientific paper

We present results of the spectral analysis of X-ray data on the 5.75 ms pulsar J0437-4715 obtained in a 25 ks observation with Chandra on May, 29-30 (2000). We supplemented the new data with those from ROSAT and EUVE. We find that all data are consistent only if one assumes a model containing two components, a thermal and a nonthermal. This model suggests that a fraction of the pulsar's X-rays originate from the pulsar's co-rotating magnetosphere, whereas the rest part of the radiation is emitted from hot polar caps on the neutron star surface. This work is partially supported by a grant from SAO.
