Absorption Features in Spectra of Magnetized Neutron Stars
V. Suleimanov, V. Hambaryan, A. Y. Potekhin +4
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 expla…
FS Aurigae: a Triple Cataclysmic Variable System containing Precessing, Magnetic White Dwarf
G. Tovmassian, S. Zharikov, C. Chavez +4
We present here results of numerical calculations demonstrating that the very long periodic variability detected in the Cataclysmic Variable FS Aur can be the result of eccentricit…
Revisiting the Parallax of the Isolated Neutron Star RX J185635-3754 Using HST/ACS Imaging
F. M. Walter, T. Eisenbeiss, J. M. Lattimer +3
We have redetermined the parallax and proper motion of the nearby isolated neutron star RX~J185635-3754. We used eight observations with the high resolution camera of the HST/ACS t…
Radiative properties of highly magnetized isolated neutron star surfaces and approximate treatment of absorption features in their spectra
V. Suleimanov, V. V. Hambaryan, A. Y. Potekhin +3
In the X-ray spectra of most X-ray dim isolated neutron stars (XDINSs) absorption features with equivalent widths (EWs) of 50 -- 200 eV are observed. We theoretically investigate d…
