Abstract (from CDS):

We have obtained a series of high resolution optical spectra of the symbiotic system CD-43 14304. We derive the radial velocity curve of the cool component and determine an orbital period of about 1448 days and a mass function of mf=0.013M☉ for this binary. We present line profiles of Hα and the Raman scattered line at λ6825 for various orbital phases. The Hα line shows very strong variations in flux and spectroscopic structure which are locked to the orbital phase. Much less variability is seen in the Raman scattered line.
