Scientific paper

We present Hα spectra of the 35.5d period Cepheid l Carinae
throughout several cycles during 1994 and 1995. A weak Hα emission
feature is present at nearly all phases, which is unusual for classical
Cepheids. This emission appears both redward and blueward of the
absorption feature at different phases.
