The Behavior of Bp He-weak Stars in the Far UV-Paper VII: HD 144334
Abstract
The analysis of 14 spectra of the B8 He-weak Si star HD 144334 recorded by the SWP camera on board the International Ultraviolet Explorer reveals variations of the far-ultraviolet spectral energy distribution shortwards of 1600 Å over a time interval of about five days in 1994 October. In contrast, the level of the mid-UV flux did not vary between phases of FUV flux maximum and minimum which suggests that changes of the silicon continuous and line opacity play an important role in the variations.
