Alpha virginis : line profiles and spectroscopic binary orbit

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in the He I (6678 A) line show that in spite of concern expressed by Lomb (1978) that the β Cephei variation was no longer active, the star is still pulsating - possibly in a non-radial mod...
