... When the pulse of ultraviolet light from the supernova hit the ring, it lit up in ultraviolet emission lines which were observed by the International Ultraviolet Explorer (IUE) . ...
... We refined the fundamental parameters of the components, the orbital periods, and the conditions of photospheric heating of the secondary component by the ultraviolet radiation of the hot component. ...
... All of the forty CCD architectures were manufactured for back-illuminated CCD operation optimized for the visible and near infrared (VIS), ultraviolet (UV), or soft x-ray (NO). ...
... Highly complex CCDs specifically developed for space applications include ultraviolet, visible and near infrared spectroscopy for atmospheric monitoring, and imaging spectroscopy for earth observation. ...
... For example, because signals tend to be low in ultraviolet passbands, the photon noise is high there, so it often happens that the default faint-magnitude limits do not allow enough very red stars. ...

... Grunhut et al. also used I U E ultraviolet and ESPaDOnS optical spectroscopy to determine the following physical parameters using the CMFGEN: Teff = 34.5 kK, log(g ) = 4.0 ± 0.2, R = 7.0+2.4 R , -1.8 M = 17+19 M , and log(M ) = -8.85 ± 0.5 M yr-1 . ...
