Ultraviolet spectroscopy of symbiotic nova V1016 Cyg with IUE and HST
Sanad, M. R.
We present International Ultraviolet Explorer (IUE) & Hubble Space Telescope Space Telescope Imaging Spectrograph (HST STIS) observations of the symbiotic nova V1016 Cyg through the period 1978 - 2000. Four spectra at different times revealing the changes in line fluxes are presented. The outflow velocity of the emitting region was calculated …
Spectral and photometric behavior of SU UMa during quiescence and outburst states
Sanad, M. R.; Saad, S. M.; Zead, I. +2 more
We report the results of spectral and photometric observations of SU UMa. Available spectra from International Ultraviolet Explorer (IUE) and CCD photometry of five nights were used. Some profiles revealing the variations of some spectral lines at different times are presented. There is variation with time for photometric observations and the brig…
Spectral behavior of the symbiotic nova AG Pegasi observed with IUE and HST
Sanad, M. R.; Bobrowsky, M.
Ultraviolet spectra from the International Ultraviolet Explorer (IUE) and from the Hubble Space Telescope (HST) of the symbiotic novae AG Peg during the period 1978-1996 are analyzed. Some spectra showing the modulations of spectral lines at different times are presented. We determined the reddening from the 2200 Å feature, finding that E(B-V) = 0…
