Scientific paper

The observation of variations in the blue absorption component of the He
I lines as well as in the Si IV 4089 emission line of HD 151932 is
reported. Possible explanations for these variations are addressed, and
it is concluded that none is satisfactory. The possibility of a
periodicity in the variations is briefly considered.
