In this work, spectroscopic observations of α Virginis have been reduced. The line profile variations observed in the He I (6678 A) line show that in spite of concern expressed by Lomb (1978) that the β Cephei variation was no longer active, the star is still pulsating - possibly in a non-radial mode. The binary orbit has been recalculated at the epoch of the observations and an analysis of this and earlier radial velocity data confirms the existence of apsidal motion and also suggests possible variation in the apsidal period. / Science, Faculty of / Physics and Astronomy, Department of / Graduate
