X-ray spectroscopy method of white dwarf mass determination in intermediate polars. External systematic uncertainties
V. F. Suleimanov, L. Ducci, V. Doroshenko +1
The masses of white dwarfs (WDs) in intermediate polars (IPs) can be determined from the shape of their hard X-ray spectra. Here we study the importance of all possible systematic…
Application of hydrostatic local thermodynamic equilibrium atmosphere models to interpretations of supersoft X-ray source spectra
V. F. Suleimanov, A. S. Tavleev, V. Doroshenko +1
Supersoft X-ray sources (SSSs) are accreting white dwarfs (WDs) with stable or recurrent thermonuclear burning on their surfaces. High-resolution X-ray spectra of such objects are…
The quiescent state of the accreting X-ray pulsar SAX J2103.5+4545
P. Reig, V. Doroshenko, A. Zezas
We present an X-ray timing and spectral analysis of the Be/X-ray binary SAX J2103.5+4545 at a time when the Be star's circumstellar disk had disappeared and thus the main reservoir…
