Descripción
Study of a sample of late-B fast rotators revealed narrow absorptions of
C IV and Si IV in the direction of 6 stars within 200 pc of the Sun. The
features are faint and narrow and in a few cases superimposed on broader
and more complex profiles. It is not clear if they originate in the
surroundings of the star or in the diffuse interstellar medium. The
FWHMs of the absorptions, in some cases at the IUE limit, point to an
interstellar origin, but nearly all the stars in which C IV and Si IV
are detected are Be and the absorptions could in fact be associated with
the extended envelope around the stars.
