Abstract

A model of a hydrogenic content of atmosphere of the isolated neutron star 1E1207.4-5209 is proposed. It is based on the assumption that the main component in the atmosphere is the exotic molecular ion and that there exists a magnetic field in the range of (4±2)×10¹⁴G. Photoionization and photodissociation correspond to two absorption features at 0.7 keV and 1.4 keV, respectively, discovered by Chandra observatory¹ and confirmed by XMM–Newton.¹¹ The model predicts one more absorption feature at 80–150 eV corresponding to photodissociation .
