Abstract (from CDS):
The observations are used to determine the parameters of the wind from the Be star. We show that a simple model, in which the wind density varies with radius as r–2, provides a good fit to the data. The wind is highly turbulent with an outer scale of ≤1010cm and an inner scale perhaps as small as 104cm, a mean density of ∼106cm–3 and a velocity of ∼2000km.s–1 at a distance of ∼50 stellar radii. We find a correlation between DM variations and the pulse scattering times, suggesting that the same electrons are responsible for both effects.
