E. Kambe, GROWTH OF THE LINE-PROFILE VARIATION REGION DURING BE-EPISODES IN LAMBDA-ERIDANI, Astrophysics and space science, 221(1-2), 1994, pp. 459-461
We have found that the range in wavelength of the line-profile variati
ons (lpv) in the Be star lambda Eridani increases by some 20% during i
ts emission phases. This growth is associated with a possible increase
in the equatorial velocity of the star during emission.
