摘要：

Results of quasi-simultaneous SWIFT and RTT-150 observations for the X-ray nova SWIFT J174510.8-262411 in May-June 2013 at the decaying phase of its outburst are presented. It is shown that the nova spectrum can be fitted in a very wide energy range (from the infrared z and i bands to hard X-rays) by a single power law attenuated due to absorption but without any traces of the presence of a soft (blackbody) component. The presence of such a component is suggested by the generally accepted models of disk accretion onto a black hole in a binary system. The observation of a single power-law spectrum may imply that synchrotron radiation from the source's relativistic jets makes a major contribution to its flux or that the accretion disk is everywhere hot, optically thin, and radiates nonthermally.
