| Abstract: | We present the results of our analysis of the observations of the intermediate polar V2400 Oph by the INTEGRAL and RXTE observatories. We reconstructed the spectrum of the source over a wide (3–100 keV) energy range. The spectrum obtained can be fitted by a computed theoretical model of the post-shock emitting region with Tmax～22 keV. As a result, we estimated the mass (0.59M⊙) and radius (8.8×108 cm) of the white dwarf in the system V2400 Oph. |
