dc.description.abstract In this thesis, data analysis of X-ray dim radio quiet X-ray pulsar 1E 1207.4- 5209 and RX J0002+6246, RX J0822-4300, CXOU J185238.6+00402 which have similar observational characteristics as 1E 1207.4-5209 are represented based on XMM-Newton satellite observations. X-ray spectral analysis of neutron star RX J0002+6246 based on XMM-Newton data is given for the first time. The problems related to the magnetic field and age of X-ray pulsar 1E 1207.4-5209 are discussed and a model is proposed to solve these problems. These four neutron stars have some common physical properties based on their observational data, and hence they may have similar physical evolution. It is shown that all of them have pure black body spectra (in three cases 2 black body components) without power law component. No pulsar wind nebula has been observed around any one of them, which strongly shows that they have low rotational energy loss despite their very small ages. All of these neutron stars are physically connected to shell-type supernova remnants which are younger than (1-2)×104 yr. None of these sources has been detected to emit at any radio frequency. These common spectral properties (and possibly common timing characteristics) of these neutron stars are examined. Their possible physical evolution is discussed and a model is proposed. As a result, it is quite possible that these objects form a new class of neutron stars quite different than the other types.
