\markboth{John Telting and Lex Kaper: Long-term periodic variability in
spectral lines of \gc}{}

\begin{abstract}
We present a quantitative study of the variability in ultraviolet 
resonance lines of \nvs, \siiv and \civ of the Be star \gcs.
For this purpose we used IUE spectra obtained over a period of eleven years.
Variability occurs in the form of discrete absorption components (DACs),
which are formed in the fast-outflowing
radiatively driven part of the stellar wind.
We constructed a template spectrum from spectra 
containing no or minor extra absorption due to DACs and modelled the
isolated DACs in the obtained quotient spectra.
Besides the frequently observed narrow components
($\vt$ typically $\leq 250$ km/s) at high velocity, we found several
broad components occurring at low and intermediate wind velocities.

We confirm the finding of Doazan et al.~(1987) who reported that the
number of observed DACs is associated with the cyclic V/R variability
of the Balmer-emission lines.
We show that when V/R$<$1 the central optical depth of DACs is
significantly lower than when V/R$>$1.
In our interpretation this is due to a correlation between the column density
associated with the DACs and the phase of the V/R cycle.

We find that the H$\beta$ observations of Doazan et al.~are consistent with a
model in which the cyclic V/R variability is due to a global, one-armed
oscillation moving through an equatorial disc.
We suggest that the higher column density of DACs in phases of V/R$>$1 is the
result of the higher density in the region of their origin, namely close to or
in the part of the equatorial disc which is rotating towards the observer.

\begin{table*}[p]
\caption[]{Results of fitting the model to residual spectra of \gcs.
Fits were made to normalized data at the spectral regions around
the \nvs, \siiv and \civ resonance doublets.
The first column gives the SWP image number of each spectrum on which a fit
was made.
For each doublet the parameters of the best-fitting (multiple) DAC model,
$\vc$, $\tc$, $\vt$, and the derived column densities, $\ncol$,
are listed.
The column density is given in units of $10^{13}{\rm cm}^{-2}$.
Velocities $\vc$ and $\vt$ are given in units of km/s.
For each doublet the fifth column lists the reduced $\chi^2$ value of
the best fit.
All quoted errors are 1\,$\sigma$ errors.}
