摘要: We report the results of spectral and photometric observations DQ Her. Available spectra from International Ultraviolet Explorer IUE, Hubble Space Telescope Faint Object Spectrograph HST−FOS CCD photometry one night were used. Some profiles revealing variations some lines at different times are presented. There is variation with time for brightness Her changed 14 mag. to 17.7 mag clear display burst. The ultraviolet luminosity emitting region in range (1.9x1031 erg s−1). mass accretion rate (3.5x10−12Modotyr−1). line flux modulations can be explained terms curtain model intermediate polars, Kim & Beuermann 1996.
