Some Properties of Stellar Transition Regions
Published online by Cambridge University Press: 12 April 2016
Extract
Among the strongest lines from stellar transition regions are the resonance lines of N V (1240Å), Si IV (1394 ,1403Å), and C IV (1549Å), which are all observable by the IUE.
In an earlier paper (Saxner, 198l) it was noticed that there is a correlation between the fluxes in these three lines. In Fig. 1 the ratio of the N V to the C IV flux is plotted against the ratio of the C IV to the Si IV flux. Verbally the correlation may be stated as follows: the Si IV flux and the N V flux are covarying; if one is strong the other also tends to be strong, and vice versa. In all cases the C IV line is the strongest.
