  • Absorption features in spectra of magnetized neutron stars 
    Suleimanov V.; Hambaryan V.; Potekhin A.; Pavlov G.; Van Adelsberg M.; Neuhäuser R.; Werner K. (2011)
    The X-ray spectra of some magnetized isolated neutron stars (NSs) show absorption features with equivalent widths (EWs) of 50-200 eV, whose nature is not yet well known. To explain the prominent absorption features in the ...
  • Carbon neutron star atmospheres 
    Suleimanov V.; Klochkov D.; Pavlov G.; Werner K. (2014)
    The accuracy of measuring the basic parameters of neutron stars is limited in particular by uncertainties in the chemical composition of their atmospheres. For example, the atmospheres of thermally emitting neutron stars ...
  • Magnetized neutron star atmospheres: Beyond the cold plasma approximation 
    Suleimanov V.; Pavlov G.; Werner K. (2012)
    All the neutron star (NS) atmosphere models published so far have been calculated in the "cold plasma approximation," which neglects the relativistic effects in the radiative processes, such as cyclotron emission/absorption ...
  • New constraints on the cooling of the central compact object in CAS a 
    Posselt B.; Pavlov G.; Suleimanov V.; Kargaltsev O. (2013)
    To examine the previously claimed fast cooling of the Central Compact Object (CCO) in the Cas A supernova remnant (SNR), we analyzed two Chandra observations of this CCO, taken in a setup minimizing instrumental spectral ...
  • Quantum nature of cyclotron harmonics in thermal spectra of neutron stars 
    Suleimanov V.; Pavlov G.; Werner K. (2010)
    Some isolated neutron stars (NSs) show harmonically spaced absorption features in their thermal soft X-ray spectra. The interpretation of the features as a cyclotron line and its harmonics has been suggested, but the usual ...
